FINAL OFFICE ACTION

TO AVOID ABANDONMENT, WE MUST RECEIVE A PROPER RESPONSE TO THIS OFFICE ACTION WITHIN 6 MONTHS OF OUR MAILING OR E-MAILING DATE.

Serial Number 76/148914

This is in response to the applicant’s communication filed on January 29, 2003. The applicant is advised of the following:

Registration was refused under Trademark Act Section 2(d), 15 U.S.C. Section 1052(d), because the mark for which registration is sought so resembles the mark shown in U.S. Registration No. 2,552,149 as to be likely, when used in connection with the identified goods, to cause confusion, or to cause mistake, or to deceive.

The examining attorney has considered the applicant's arguments carefully but has found them unpersuasive. For the reasons below, the refusal under Section 2(d) is hereby made FINAL.

The test for determining the likelihood of confusion has been previously set forth. However, for convenience, the same will be reiterated here.

In determining whether there is a likelihood of confusion, the examining attorney must consider all circumstances surrounding the sale of the goods. Industrial Nucleonic Corp. v. Hinde Engineering Co., 475 F.2d 1197, 177 USPQ 386 (CCPA 1973). These circumstances include the marketing channels, the identity of the prospective purchasers and the degree of similarity between the marks and between the goods. In comparing the marks, similarity in any one of the elements of sound, appearance or meaning is sufficient to find a likelihood of confusion. If the goods of the parties differ, it is necessary to show that they are related in some manner. In re Mack, 197 USPQ 755 (TTAB 1977).

First, the marks should be considered similar. The applicant's mark is NEO; and the registrant's mark is NEOS. The only difference between the marks is the addition of the letter “s” in the registrant’s mark. The marks create the same commercial impression. The applicant has referenced the existence of other registrations that contain the term NEO. Since copies of registrations were not provided, these registrations are not part of the record and have not been considered. In re Hungry Pelican, Inc., 219 USPQ 1202 (TTAB 1983); In re Delbar Products, Inc., 217 USPQ 859 (TTAB 1981); Editorial America, S.A. v. Gruner & Jahr AG & Co., 213 USPQ 498 (TTAB 1982); In re The Library Restaurant, 194 USPQ 446 (TTAB 1977); In re Duofold Inc., 184 USPQ 638 (TTAB 1974).

Second, the parties' goods appear to be related. The applicant's goods are “electro-optical components, namely, transmitters, receivers, connectors, adapters. filters. switches, terminators, resonators, lasers, waveguides, and multiplexers; optical fibers; optical devices, namely, transmitters, receivers, filters, splitters, multiplexers, and couplers; optical wave guides; optical network components, namely, lasers, detectors, cables, resonators, modulators, connectors, switches, multiplexers, routers, filters, phase-shifters, amplifiers, and splitters; and optical coated substrates”. The registrant's goods are “accousto-Optic (AO) components, namely, modulators, deflectors, Bragg cells, Q-switches and mode lockers all with Radio Frequency (RF) drivers as complete turnkey systems of original equipment manufacture (OEM) modules which include mechanical translation stages for their micropositioning for manufacture of Photolithographic masks in the field of Hybrid circuit manufacturing; Electrical instruments, namely, AO one- and two-dimensional scanners and submicron laser machining centers consisting of AO Scanners and modulators and optics for use in the field of Research and Development; Computer software for use in motor control operating AO scanners, and for use in chemical and electrical testing in the field of Chemical Spectroscopy”. The goods are related because the enclosed evidence of record indicates that electro-optical and accousto-optical technologies are used together in the optical applications field. The contention is supported by the attached evidence obtained from the Nexis database. (See enclosed).

Lastly, the parties' channels of trade are related due to the nature of the goods. The same purchaser in the form of a company that does business relating to the optical applications field, such as lasers, would encounter the similar marks used in connection with the parties' related goods and would presume that the goods emanated from the same source. Confusion as to source would therefore be likely.

Accordingly, based on the evidence and authorities stated above, the refusal to register is maintained and made FINAL.

Please note that the only appropriate responses to a final action refusal are either: (1) compliance with outstanding requirements, if feasible, or (2) filing an appeal to the Trademark Trial and Appeal Board. 37 C.F.R. Section 2.64(a). If the applicant fails to respond within six months of the mailing date of this refusal, this Office will declare the application abandoned. 37 C.F.R. Section 2.65(a).

... layer. They make decisions about where signals are routed, on what wavelengths they travel, and what happens in the event of network failures. The ability to move signals from one wavelength to another is crucial. In the next few years, this will be enabled ideally via tunable lasers and a single OEO (optical-electrical-optical) conversion. In the future, this could be implemented using a tunable laser and a tunable all-optical 3R (reamplify, reshape, retime) wavelength converter.

Like the SONET ADM, with an OADM some signals are added/dropped and others pass through. The first generation of OADMs, which are still being deployed, was static-designed and ...

Depending on the design of the ROADM and its required scalability, different tunable components might be used. One design involves full signal demultiplexing and switching at the optical level. Larger, integrated tunable multiplexers will help alleviate cost concerns for this architecture. A second design cascades multiple, single-channel add/drops, each unit of which utilizes tunable filters. Tunable lasers are required for both configurations.

OXCs and ROADMs are enabled by tunable optical components. As optical networks mature, these tunable components will be joined by other emerging technologies that allow the optical network to adjust to future bandwidth demands.

Much of the ...

... network management features will break the barrier into cost-effective deployment.

Designing an optical component to be agile in the wavelength domain is more challenging than designing it for a specific wavelength. The cornerstone components in optical networking are lasers (sources), wavelength-selective devices (e.g., filters, gratings) and detectors (receivers). Of these, only the detector is intrinsically able to operate over a number of different wavelengths (though there is no intrinsic ability to select a specific wavelength). Much of the work in optical components has been aimed at creating tunable lasers and wavelength-selective devices (see Figure 2).

A signal's ability to change wavelengths dynamically at the edge and/or in the network core is the first step in implementing the intelligent photonic layer. Tunable lasers will be the first wavelength-agile components to enable this disruptive shift in network functionality.

Tunable lasers have been studied in the academic world for more than a decade; they are now fundamentally changing the way optical networks are designed and built. The requirements for packet-switched networks are strict in terms of sub-microsecond switching speeds; true IP over optics, though undoubtedly a reality in the future, is not likely to be deployable for several years. As a result, the current focus for tunable lasers is on circuit-switched applications.

There are several methods for creating a widely tunable laser; among the most successful are:

DBR-based (distributed Bragg reflector) designs, such as the grating-coupled sampled reflector and the sampled grating DBR, which use electrical current as the tuning mechanism.

MEMS-based designs, typically VCSELs (vertical cavity surface emitting lasers), which use miniature movable mirrors as the tuning mechanism.

ECL-based (external cavity laser) designs that rely on movement of an external grating as the tuning mechanism.

Tunable lasers are fabricated using complex methods and require sophisticated and integrated control circuitry. A number of vendors are beginning to produce field-quality devices in large quantities, which will help achieve economies of scale. While these devices are mature enough to be deployed, performance will continue to improve. In particular, optical output power over a wide tuning range (i.e., C+L bands) will likely show marked enhancement in the next year.

Tunable filters have also been in development in the academic world for well over a decade. Two of the most heavily studied methods are the AOTF (acousto-optic tunable filter) and the mechanically tuned FBG (fiber Bragg grating). Many others also show great promise for meeting strict performance requirements, including EOTFs (electro-optic tunable filters), tunable MEMS-like DBR cavities, and tunable semiconductor cavities.

Simple applications for tunable filters include use as noise filters and channel selectors. Receivers are inherently broadband, but they cannot select one particular wavelength, so the inclusion of a tunable filter will be necessary for wavelength-specific operation.

Tunable filters are critical in ROADM applications. When designing a ROADM, careful consideration must be paid to the impact of adding/dropping channels on other signals. Key considerations are insertion loss (the amount of optical power lost while traversing the device) and crosstalk (the amount of optical power from adjacent channels that leaks into the desired channel). Both parameters depend almost exclusively on the filtering mechanism used, so the demands placed on the tunable filter are quite strict.

To traverse an optical network, a signal is required to travel over different wavelengths. On the edge, the signal might use 1310 nm. In the core, the signal typically uses a wavelength in the 15XX-nm ...

... cause excessive network degradation, and dynamic network reconfiguration will be heavily constrained by optical path length.

Today, wavelength conversion with 3R functionality is inherently an OEO process that is just beginning to reach economic feasibility using tunable lasers. Although there is the perception that tunable, all-optical, 311 wavelength conversion is desirable, the loss of performance monitoring capabilities remains a drawback. The tunable networks of the future will contain elements with single OEOs; tunable, all-optical, 3R wavelength conversion, when ...

Most optical wavelength converter endeavors utilize the nonlinear properties of semiconductor optical amplifiers, devices that are still undergoing growing pains to overcome performance issues. Devices lacking the retiming feature, known as 2R (reamplify, reshape), are inherently easier to design and manufacture, and show promise for future integration with the more complex optical clock recovery (the ...

... scalability. There are still questions regarding longterm reliability and optical insertion loss.

Electro-optical switches use highly birefringent substrate material and electrical fields to redirect light from one port to another. A popular material used in an electro-optical switch is lithium niobate. An electrical signal is fed as the control into the device's substrate. This electrical field changes the substrate's index of refraction, which manipulates the light through the appropriate waveguide path to the desired port. Opto-electrical switches are fast and reliable, but have high insertion loss and possible polarization dependence.

Acousto-optic, SOA (semiconductor optical amplifier) and ferro-magnetic are other types of switches. Acousto-optic switches receive acousticwave-induced pressure from a RE-fed piezoelectric transducer to generate fine gratings in optical waveguides. The gratings diffract lights to the desired port. SOA technology uses semiconductor-based amplifiers that operate in the gain-clamped mode with some types of interferometric switch geometries to optically switch.

Notes to Editors

Scientists at the Lawrence Livermore National Laboratory will focus the output of the laser onto small deuterium and tritium targets to study nuclear fusion. What they learn will give greater understanding of the ageing nuclear weapons stockpile, and help keep it safe and reliable in the absence of nuclear testing. NIF will also perform important research in fusion energy development, astrophysics and basic science. The "tripler" plates from Cleveland Crystals will be used to convert the output of the worlds largest laser into the ultraviolet part of the spectrum to make the fusion process more efficient.

Lawrence Livermore National Laboratory is one of the world's largest users of high quality optics, crystals, electro-optics and acousto-optics, all of which are key products of the Gooch & Housego group of companies. As a result a close relationship is developing and regular discussions, meetings and visits are taking place with aim of developing the business in each of these areas.

Developments in electro-optics may soon be pushing photons further into the network, taking over some of the switching and routing tasks performed exclusively by electrons today.

... frequency-selective, distributed reflection that is related to the spacing within the grating. A fiber Bragg grating's low-loss characteristics, as well as its ability to selectively pass or reflect specific frequencies, make it a very versatile element that can be used in filters, demultiplexers, mixers, and other sub-systems of a WDM network (Fig. 2).

The Building Blocks

Even before all the bugs have been worked out, these and other elements have been pressed into service to make all kinds of functional building blocks for optical networking systems. Most of these bear close resemblance to their electrical counterparts. Some examples of light-on-a-chip devices that are currently available or under development include:

Filters. Rating-based filters can be used to select desired wavelengths out of a WDM stream, or block a particular channel from being injected into an add-drop multiplexer. Several technologies also are available to produce tunable optical filters. Fabry-Perottype devices use a resonant cavity between two mirrors to couple a pair of waveguides at a particular frequency. The cavity's transmission peaks can be changed by either using MEMS techniques to alter the cavity length, or by changing the absorption characteristics through the use of ferroelectric-type liquid-crystal materials. In addition to the aforementioned Mach-Zehnder devices and fiber Bragg gratings, electro-optical and acousto-optical effects can be exploited to produce filtering functions.

Semiconductor lasers can be made into very effective filters for some applications. Just operate them below their threshold point and run a signal through them. Their sharp and narrow filter characteristics, as well as their ability to produce gain and filtering simultaneously, make these devices quite intriguing.

Switches. On/off switches can be created using many technologies, including MEMS-based moving reflective membranes, polarizing materials, and Mach-Zehnder- ...

... create complex multistage switching networks. At present, high levels of attenuation make it difficult to run a signal through more than three or four switch stages, but work on improved materials and structures is under way.

Multiplexers/demultiplexers. WDM relies on being able to combine light from multiple sources, as well as extract a particular channel from a WDM beam. Today's passive optical networks (PONs) depend on elegant passive structures, such as phased-array waveguide multiplexers, to perform these tasks (Fig. 3). These de vices consist of a series of different-length waveguides coupled at each end to a set of free-space optical cavities. A WDM signal that's entering the cavity from one of several fibers is ...

... output fiber. This avoids having two channels with the same wavelength on the same fiber (Fig. 3, again).

Currently fabricated primarily as discretes in low volumes on silica substrates, these structures form the heart of most WDM add-drop multiplexers available on the market. In the future, such a multiplexer could be built on top of a GaAs substrate, opening the possibility of a single hybrid electro-optical chip with optics, photodetectors, and lasers. If such a device incorporated the multifrequency lasers now under development (as described in the next section), it could form a significant chunk of a WDM switch element.

Integrated optical amplifiers. The first practical all-optical amplifiers used large spools of erbium-doped fiber that were pumped with laser energy to regenerate weak network signals. Obviously, it's rather difficult to cram 30 meters of fiber on a chip, so an alternative was developed. The most common, integrated optical-amplifier structure consists of a forward-biased heterojunction which carries current. Typically, it also has a set of optical waveguides that contain the incoming signal within the junction's active region. This provides amplification (Fig. 4). The structure is faceted on either end to make a resonant cavity, allowing stimulated emissions which are in proportion to the input signal.

These semiconductor optical amplifiers (SOAs) can be used simply for amplification, or tuned to provide frequency conversion. This ability to shift frequencies can be exploited to build many kinds of WDM switching architectures. Tunable versions of SOAs are under development.

Combined with wavelength-tunable optical receivers, it's now possible to build frequency-agile nodes that can efficiently send and receive traffic across a shared WDM infrastructure. If SOAs can be successfully integrated into electro-optical chips, the performance and flexibility they offer should permit commercial versions of ...

Other proposed active systems use frequency-recognizing receivers and frequency-agile transmitters in conjunction with free-space crossbars or waveguide-based switch matrices. In any case, even the slowest and crudest of these systems hovers at the top end of any electron-only switch available.

Information on Cleveland Crystals

-----------------------------------------------------------------------

Cleveland Crystals manufacturers high quality optical crystals and

electro-optic devices. Their principal products are: -

-----------------------------------------------------------------------

- Very large crystals for use in laser induced nuclear fusion research,

- Electro-optic Q-switches, otherwise known as Pockels cells, which are used in industrial and scientific lasers to generate high power optical pulses,

- A wide range of specialist crystals whose optical and electro-optic properties are critical to the operation of, for example, tunable lasers and optical detectors.

Cleveland Crystals are widely regarded as the leader in each of these fields.

As an example, Cleveland Crystals' large aperture (40cm) potassium dihydrogen phosphate (KDP) crystal plates will be used in the world's largest laser, which is currently under construction as part of a $1.2bn project. In order to enable Cleveland Crystals to supply the volume of crystals needed, $5.6m is being invested by the US government in state-of-the-art equipment to be located in a new ...

... Gooch & Housego's UK operation. The acquisition of Cleveland Crystals will not only increase Gooch & Housego's profile, it will enable the company to become a 'strategic partner', providing several critical components of the final system.

The Pockels cells or electro-optic Q-switches, which account for approximately 50% of turnover, perform the same function in a laser as Gooch & Housego's acousto-optic Q-switches. (A Q-switch is a device used to boost the output power of a laser by around 1000 times, thus making it a useful industrial, medical or scientific tool.) The two technologies complement, rather than compete with, each other and will allow the Gooch & Housego group to address the full spectrum of Q-switch applications. ...

... common to both companies.

Cleveland Crystals are experts in the growth of many types of crystals and utilise a variety of growth techniques. These crystals are 'designed' to have specific properties, which are exploited for a diverse range of applications from military counter measures to tunable lasers. Applications for such lasers include spectroscopy, remote sensing, medicine, materials processing and laser radar.

Reasons for the Acquisition

In summary, the Acquisition of Cleveland Crystals is strategically important to Gooch & Housego in three ways:

1. Cleveland Crystal's business in crystals for laser applications fits in with Gooch & Housego's planned expansion into the US market for large aperture crystal and glass optics. (G&H will start manufacturing optics in Orlando, Florida at the Optronic Laboratories Inc plant this year.)

2. The range of electro-optic Q-switches manufactured by Cleveland Crystals is complementary to G&H's range of acousto-optic Q-switches and will reinforce dominance of this market.

3. Access to a supply of world class crystals of many types will allow G&H to extend its activities into devices based on non-linear optics, electro-optics and other technologies previously not easily accessible due to material supply issues. It will also potentially allow G&H to become self-sufficient in crystals for its acousto-optic products.

The significant sales of large KDP crystals expected over the next several years combined with the injection of state-of-the-art equipment and technology will be drive considerable growth in the business, further elevating it beyond the level of its few competitors. ...

BODY:

... technical impediments remain, restricting its application in a broad area, as was promised initially. The most noticeable obstacle has been the slow recording rate of conventional holographic techniques, which record spatial interference patterns generated by two temporally co-existing laser beams. The recording requires, in addition to laser excitation, subsequent electron diffusion in storage materials, as in the case of photorefractive memory, for example. Such processes limit photorefractive technology to applications that are not input intensive, such as memory that is written only once. Success in developing high-performance ...

... O intensive applications(5, 6). This memory not only has features common to conventional spatial holographic recording, such as high capacity and high degree of parallelism, but also some that are complementary to conventional holography, including fast page recording speed and modest laser power requirement. Recent experiments(6) show that an exposure time of several microseconds and a peak laser power of less than 200 mW are sufficient to record a high-resolution binary image with the time-domain technique.

Historically, the time-domain holographic approach evolved from an optical transient phenomenon known as stimulated photon echoes(7). It is ...

... a reference beam and a data beam. These two beams interfere at a recording medium, causing a change of the optical properties of the medium. Unlike in spatial holography, the reference and data beams appear in the form of short laser pulses and do not overlap temporally. In most recording schemes developed to date, the reference pulse precedes the data pulse by several nanoseconds to several microseconds to provide, in addition to a spatial reference, a temporal reference for the recorded holograms (Fig. 1). The interference generated by these two temporally distinct laser pulses occurs in both spectral and spatial domains, giving rise to four-dimensional holograms(8).

The spectral interference of the two pulses is recorded in a storage medium [which is often a rare-earth-doped solid such as [Eu.sup.3+] [Y.sub.SiO.sub.5], or [Pr.sup.3+]:YAG (YAG, yttrium-aluminum-garnet)] by laser excitation. Ions such as [Eu.sup.3+] and [Pr.sup.3+] that are responsible for data recording are resonantly excited by the laser pulses to form population gratings that resemble the Fourier spectra of the pulse pair (Fig. 2). These gratings in a carefully chosen material can persist for several hours to perhaps several days at cryogenic temperatures because the recorded information is actually stored as population modulation of hyperfine levels in the ground state(6). Because the grating is a direct result of resonant excitation and requires no secondary process, its formation is instantaneous and requires modest laser power; the data recording is therefore inherently fast and efficient, giving rise to high data transfer rates, fast access times, and short latency. These features are ideal for applications such as a dynamic memory.

Data stored as population gratings are retrieved by illuminating the sample with another laser pulse known as the read pulse (Fig. 2), which reconstructs the object field as in conventional holography. However, unlike in conventional holography, the reconstructed field appears as an emitted laser pulse and is temporally distinct from the read pulse, just as in case of recording. For a given temporal separation [Tau] between the write and data pulses, the reconstructed pulse will occur a time [Tau] after the arrival of the read pulse ( ...

... crystal was kept at a temperature of about 4 K in a flowing Hevapor cryostat.

Digital data pages, each of which contained 3360 bits of data, were generated by illuminating a spatial light modulator (SLM)(10) with laser pulses as short as 11.2 [Mu]s(11), giving rise to a maximum peak (burst) recording rate of 300 megabits per second. Each page was stored in a distinct, narrow ( 500 khz) frequency channel(12) ...

... absorption line by wavelength-division multiplexing (WDM). The separation between two adjacent channels was chosen to be 800 kHz. There are distinct advantages to WDM(13): (i) Recording and retrieval can be accomplished without the use of any moving parts for laser beam steering, so that it is inherently reliable and often provides short access times(12); (ii) there is no significant effect on diffraction efficiency; and (iii) each data page can be recorded in an identical manner, eliminating the ...

... 300 megabits per second permitted by the storage material; however, this limit is not fundamental. High-speed SLMs with a full frame rate of 3 kHz are commercially available; ones with higher speeds are being considered for development. Semiconductor laser arrays may be used in the future to compose binary digital pages without the need of SLMs. Such devices will have a single-channel modulation rate sufficiently high (in excess of 1 GHz) to match the burst rate set by the ...

... bit dimensions in the case of parallel recording. For a given frame size, it translates into a decrease of the data transfer rate.

For an optical storage system operating at high I/O speeds with low laser power illumination, the retrieved data are often at a signal level that is limited by shot noise, which is a result of the quantum nature of photons. For page-formatted recording, the process is further complicated by the non-uniform illumination of an ...

... system often exhibits large page-to-page fluctuations and intrapage variations.

Figure 3A shows a sample input page used in data recording. Spatial variation of the intensity is apparent. This variation reflects the spatial beam mode of the addressing laser, contributing partially to the spatial signal variations within a page discussed earlier. The other contributions include shot noise.

The page-to-page fluctuation is often more noticeable in the retrieved data because it is magnified by less-than-ideal recording and ...

The intensity difference between the two pages is [is greater than] 300%, which is mainly caused by the frequency instability of the laser system(12).

Examination of the histogram of all 100 pages (totaling 336 kilobits of data) reveals that the intensity distributions of the 1's (or ON's) and 0's (or OFF's) partially overlap (Fig. 4A). If a single threshold were used to determine all of the data ...

... fundamental difference between the present technique and the persistent spectral hole-burning (PSHB) holographic recording [see, for example, A. Renn et al., J. Lumin. 38, 37 (1987)] is that in PSHB, the sample is exposed simultaneously to two laser beams and a spectral hole is burned at the laser wavelength. The depth of the hole at a given spatial location varies according to the spatial interference pattern generated by both beams, and no temporal information is recorded in the holograms. These holograms are known as volume holograms, identical to those obtained in ...

... length of the data pulse varied from 11.2 to 50 micros. This pulse was biphase-modulated with pseudorandom code [Y. S. Bai and R. Kachru, Opt. Lett. 18, 1189 (1993)] to reduce coherent saturation as well as echo fluctuations caused by laser wavelength instability. The write and read pulses were 10-[Mu]s-long square pulses with a peak power of only 200 mW. These pulses were also biphase-encoded but with the 5-bit Barker code [see, for example, M. N. ...

(12.) To achieve the required frequency precision, we used a Coherent ring dye laser and further frequency-stabilized the laser by using the Pound-Drever-Hall method [R. W. P. Drever et al., Appl. Phys. B 31, 97 (1983)]. By using an intracavity electro-optic modulator and locking the laser to an external reference cavity, we substantially reduced laser noise with frequencies above 1 kHz arid achieved a laser linewidth with respect to the cavity of 4 kHz over a time period of 20 ms. We accomplished WDM by tuning the laser externally with an acousto-optic modulator to achieve a channel access time of 1 [Mu]s.

... cause the film-cantilever structure to bend to minimize its stored strain energy. If, for instance, the tensile stress in the film deposited on the top surface of the cantilever increases, the film tends to contract and the cantilever bends up.

We focused a probe laser onto the end of a cantilever and measured the bending of the beam by the movement of the reflected laser spot on a position-sensitive photodiode; the deflection of the cantilever is linearly dependent on the current output. We used commercially available V-shaped atomic force microscope microcantilevers. They are fabricated from silicon nitride with typical dimensions of 200 [Mu]m in length, 20 [Mu]m in width, and 0.6 [Mu]m in thickness, and the bottom surface is coated with a thin layer of gold ( 20 nm thick) that increases the optical reflectivity for the probe laser beam. A thin amorphous [As.sub.50][Se.sub.50] film (250 nm thick) was evaporated on to the top surface of the cantilever. As demonstrated previously (7, 8), a composite cantilever is sensitive to thermal changes, for example, when heated by another laser beam incident on the top surface. This phenomenon, the bimetallic effect, results from the differential thermal expansion of the two bonded materials. The total stress change in a deposited film is therefore the sum of two components: the internal and thermal stresses. The internal stress is related to differences in the structure, which, for this experiment, was modified by a change in polarization of the light incident on the chalcogenide film. To differentiate between these two types of stress, we periodically chopped the illuminating pump laser beam and recorded the ac and dc components of the measured signal separately. The synchronous response of the cantilever to thermal fluctuations is very fast [less than 1 ms in air (8)]. The amplitude of the resulting signal is proportional to the power effectively absorbed by the sensor. The latter was ...

... throughout the experiment. The recorded dc signal represents the changes in internal stress, which occur much more slowly than the response to thermal variations.

Microcantilevers were mounted onto the head of an atomic force microscope (Fig. 1). The film was illuminated with a He-Ne laser beam, square-wave modulated at about 50 Hz by an acousto-optic modulator (AOM), and then polarized by an electro-optic modulator (EOM). The polarized light was guided through a polarization-preserving fiber that was positioned to illuminate the whole top chalcogenide surface of the cantilever. The typical polarization ratio at the output of the fiber was 1:50. The EOM allowed the transmission of one of two orthogonal ...

Compared to a conventional CD laser beam recorder, the dual beam specification calls for improvements in the radial drive, the rotation module and the vibration isolation performance. The tight radial requirements were realised by using a new friction drive - the new design providing increased stiffness with a completely play-free construction. The drive also uses improved components and has a closed loop position control with a high resolution laser scale.

The rotation air bearing has also been completely redesigned and now provides increased stiffness and improved mass distribution. The vacuum table, which holds the master disc, is integrated into the bearing design, resulting in radial and axial run outs being reduced by ...

As far as the modulation and deflection are concerned, either acousto- optic (AO) or electro-optic (EO) devices can be used. Each type has its own advantages and disadvantages. AO modulators, for example, are very compact and are easy to control. EO modulators, on the other hand, are more difficult to control when the recording signal has a variable DC content, which is the ...

AO devices, however, are the preferred choice for fitting the modulator onto the moving carriage, given the space limitations. Wavefront aberrations, which can be introduced because the beam is actually focused in the AO modulator, are removed by using a pinhole as a spatial filter.

An important element in the optical system is the laser. Among the industrially available laser sources, argon (Ar) and krypton (Kr) ion lasers have found widespread use due to their power output and noise characteristics. These lasers offer a choice of wavelengths in the blue and UV area of the spectrum.

The desired resolution can be obtained by several combinations of NA and wavelength, as shown in Table 2 (above). For example, in combination with a NA 0.9 objective, a Kr ion laser operating at 413nm (the blue area of the spectrum) can do the job easily. This visible wavelength means that well proven AO modulators can be used.

In order to provide a smooth migration path towards even shorter wavelengths, all the ...

HEADLINE: High Spectral Purity from Single Crystal

BODY:

A single-crystal, self-Q-switched, solid-state laser that generates nanosecond to sub-nanosecond pulses with a high degree of spectral purity and intensity stability has been developed by researchers at Hunter College of the City University of New York (CUNY, New York State Center for Advanced Technology, Ultrafast Photonic Materials and Applications, 79 Fifth Ave., New York, NY 10003; Tel: 212/650- 6960). Q-switched lasers are widely used in applications such as remote sensing, material processing and medical surgery. They normally require the use of electro-optic or acousto-optic modulators, or Q-switches, inside the laser cavity. These light modulators are usually bulky and expensive, and their operation requires high-voltage drivers or radio-frequency amplifiers.

A laser can initiate passive Q-switching if the cavity contains saturable absorbers. These absorbers must be made of materials that have low light-transmission levels when laser intensity is weak, but become transparent when laser intensity is high. Passive Q- switching is simple in configuration. However, it is considered unreliable because the commonly used saturable absorbers, organic dyes and color centers experience degradation and fading problems.

The self-Q-switched lasers invented by Ying-Chih Chen's group at CUNY utilize chromium neodymium:yttrium-aluminum-garnet (Cr,Nd:YAG) crystals. The Nd ions generate the stimulated emission at 1064 nanometers (nm) and the Cr ions act as saturable absorbers. By combining the functions of gain medium and saturable absorbers into one crystal, the Q-switched lasers are self-contained and can be made very compact. The lasers developed at CUNY consist of a single Cr,Nd:YAG crystal a few millimeters in length with reflective coatings deposited on opposite ends of the crystal.

The CUNY group uses a high-power semiconductor laser operating at 808 nm as the pump source. The laser produces short pulses at 1064 nm, which are intense enough to generate second harmonic emissions with a 40% conversion efficiency with an unfocused beam. The pulse duration ranges from sub-nanosecond to a few nanoseconds, depending on cavity length and the concentration of the absorbers. With no moving parts in the cavity, the monolithic laser is extremely stable. Pulse-to-pulse intensity fluctuation is less than 0.25%. After long periods of testing, the saturable absorbers were chemically stable and had not faded.

Nd:YAG lasers of similar dimensions would normally operate in multiple longitudinal modes due to spatial hole burning, an effect characteristic of linear cavities. Single longitudinal mode operation in solid-state lasers requires the use of frequency- selective components, such as gratings or etalons, unless the cavity is very short. A unique feature of the self-Q-switched lasers is that they always operate in a single longitudinal mode.

The CUNY researchers attribute the single-mode operation to the establishment of self-induced loss grating in the cavity when the standing waves of the dominant lasing mode bleach the saturable absorbers. The self-induced grating enhances the dominant lasing mode and rejects adjacent longitudinal modes, just as man-made grating does in distributed-feedback semiconductor lasers. This single longitudinal mode characteristic makes these lasers very attractive as master oscillators for the injection seeding of high- power lasers.

At present, the pulse energy of the self-Q-switched laser has reached 100 microjoules in a diffraction-limited beam. CUNY researchers are working on the next versions of the devices, which they believe will produce pulses with energies greater than one millijoule and with even shorter pulse duration, while preserving the virtues of ...

Over the 0.6 to 1.5 GHz band, the response of any of the 16 outputs is flat to + or - 0.5 dB.

However, matching the responses of the output TRAMs is a significantly more difficult task than matching conventional voltage amplifiers.

HEADLINE: EYEBALLVISION, ANYONE?

BODY:

Is the laser-scanned eyeball the future of virtual reality? Tiny laser beam in eyeglass frame substitutes for picture tube in patent application by Motorola.

Motorola has declined comment on proposed uses for invention, except to say it's "too early" to talk about it, but did note that "direct view and virtual display will play an increasing role at Motorola in the future," and laser system is "one of many avenues" it's pursuing.

Bureau of Radiological Health, part of U.S. Food & Drug Administration, which has authority to approve or ban products using lasers and other potentially hazardous devices, wasn't saying anything, either. Our request for comment on what Motorola would have to go through to get approval received no reply.

Invention by 3 scientists at Motorola Semiconductors in Phoenix involves, according to patent application, "a display which writes an image directly on the retina of an eye." Application states: "The display includes a laser which produces a collimated light beam that is modulated with video information and is then scanned and directed through the eye pupil to produce an image on the retina. The scanning uses micromachined mirrors, electro-optic or acousto-optic devices which are extremely small and require very low power."

Accompanying drawing shows scanner built into temple of spectacles, emitting laser beam reflected from lens of glasses into eye. Device incorporates semiconductor laser in pocket pack. Light passes through fiber cable to scanner.

HEADLINE: Binary optics for laser beam scanning; part 2

BYLINE: Jain, Anil K.

BODY:

... optics. The first part, concerning binary optics as beamsplitters, appeared in September, on page 28).

The need to scan a beam of light is not new; it dates back at least as far as the first lighthouse. Since the advent of the laser and its use in applications that require precise positioning of a light beam, however, the level of sophistication required of a scanner has grown tremendously. There are many such applications, including bar code scanners, laser printers and copiers, optical recording, and inspection.

... Typical scanners can be classified into two basic categories, depending on whether or not they contain moving parts. In the former group, we place rotating mirror and grating wheels as well as oscillating galvanometer, torsional, and resonant scanners. The latter group includes acousto-optic and electro-optic scanners. As noted below, and in Table 2, these devices have their individual advantages and TABULAR DATA OMITTED disadvantages.

Scanners with moving parts typically sweep mirrored surfaces by mechanical means. Therefore, they are characterized by broad spectral bandwidths and relatively large ...

... frequencies and cannot be used to access any desired point in scan space. All oscillating scanners are limited in scan speed by the high mechanical accelerations required at the ends of the scan.

Scanners with no moving parts, employing acousto-optical or electro-optical phenomena, can have very high scan speeds since there is no mass that requires acceleration. The physical effects upon which they are based, however, tend to be small; this results in very limited scan angles, typically on the order of tens of milliradians.

... only be achieved through the use of multiple layers in the binary optics; this involves added processing steps, which in turn raises the cost of these components.

Conclusion

Binary optics technology provides great control over many of the desired parameters in laser scanner design. Scanners built using this technology are compact and rugged. They solve many of the technical problems associated with more conventional techniques, and can perform beam manipulations that are nearly impossible using any other techniques. They are ideal for applications using lasers or laser diodes when multiple output beams are required.

For years, engineers puzzled over a problem: How to build machines with sensitive electronic components that will not suffer distortion when operated in an electromagnetic field. Such fields show up around radar and radio transmitters, causing unwanted currents to flow in metal wires and cables.

... system means you don't have to worry about electromagnetic interference," says Daher, who described the study at a July symposium at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

The researchers tested four types of photonic devices -- electro-optic, acousto-optic, magneto-optic, and charge-coupled devices -- all of which use light as the primary means of information transmission. These devices sense energy in one form (sound, magnetic pulses, etc.) and convert it into another (light, electrical pulses, etc.). Yet, when ...

New dyes, filter techniques now enable scientists to observe subcellular processes in living cells.

Digital image processing has had an enormous impact on biomedical microscopy. Initially, image processing improved contrast, making possible observations of structures that were invisible using ...

... light source, a full-color image is observed, limited by the spectral characteristics of the microscope optics, light source and detector. With a standard monochrome video or CCD camera, spectral information is obtained only by inserting a bandpass filter that selects wavelengths matching the absorption band of the dye.

In fluorescence microscopy, different wavelengths are used to excite and detect dyes using an optical path shown schematically in Figure 2. A bandpass filter selects the excitation wavelengths of the fluorescent dye. The excitation light reflected from a dichroic mirror passes through the objective and is focused on the specimen. The fluorescence is then collected by the objective, transmitted by the dichroic mirror and focused through a secondary bandpass filter that selects the emission wavelengths of the dye. With careful isolation of the excitation and emission wavelengths, an image is observed with a dark background and only areas containing dye are visible.

Filtering light

Multispectral measurements can be accomplished using a number of commercially available monochromator designs. Besides traditional filter wheels and grating spectrophotometers, two new approaches have been introduced in the past few years. One of these is the acousto-optic tunable filter (AOTF). The other, even more recent, is the liquid crystal tunable filter (LCTF).

Throughput is probably the most important parameter when considering a filtering device. In fluorescence applications, the emitted light levels are extremely low (nanowatts to picowatts per square centimeter). Intensified cameras are usually required for image acquisition, ...

... throughput as the product of the quantity defined above times the transmission and the bandpass width (in nanometers). Estimating throughput for a particular microscope experiment is difficult.

So, rather than calculate absolute throughput, it is usually more informative to compare the tunable filter in question to interference filters that have been used successfully in similar experiments. The relative values of the parameters used to calculate throughput for monochromators discussed in this article are given in the Table.

(Incomplete data In Original Publication)

is optical contrast as calculated by the ratio of in-band to out-of-band flux. Assuming a uniform illumination and uniform spectral response of the detector, this ratio is usually determined by dividing the area under the transmission curve by the area outside the bandpass.

Conventional methods

Traditional mechanical filter wheels are the most widely used monochromator for multispectral imaging. They are available from several sources and are easily attached to excitation light sources or inserted between the microscope and the camera. They have from three to ten slots for standard 25-mm-diameter interference filters. The out-of-band rejection, image resolution and peak transmittance of such filters are high. The disadvantages presented by filter wheels are fixed wavelengths, image shift due to wedge, relatively low switching speed (0.1 to 0.5 s) and vibration, which can be a problem in living cell experiments. Interference filters also deteriorate when exposed to heat and intense light.

TABULAR DATA OMITTED

... emission from one small element of an image. A moveable aperture of variable size allows choice of the image element. Also, single-element detectors, such as photomultiplier tubes and silicon detectors, can be used to provide very high sensitivities.

Acousto-optic tunable filters

Acousto-optic tunable filters have been under development for more than two decades(1,2,3) and are now maturing as a commercial product (Brimrose, Crystal Technology, Inrad, Panasonic). In AOTFs, a radio-frequency sound wave generated by a piezoelectric transducer passes ...

... side-lobes outside their bandpass. These can be reduced to approximately 3 percent of peak transmission by amplitude apodization of the RF drive signal. This is important when considering out-of-band signal.

AOTFs have proven very useful for selecting individual lines from multiline lasers in fluorescence excitation.(4) The small beam diameter, high degree of collimation and polarization of laser beams work very well with AOTFs, providing out-of-band rejections of (10.sup.5), and high efficiency greater than 90 percent.

AOTFs have also been used for filtering light from lamps for bright-field illumination.(5) Generally, a well ...

... a potential problem of image shift. This would be detrimental to multispectral imaging applications requiring precise image-to-image registration. However, imaging experiments have been performed in the near-IR in areas such as Raman microscopy(6) and astronomy.(7)

Liquid crystal tunable filters

Liquid crystal tunable filters (LCTFs) are a new technology developed at CRI Inc. The LCTF is a birefringent filter, which uses the retardation in phase between the ordinary and extraordinary rays passing through a crystal to create constructive and destructive interference. By stacking several stages in series, a single passband is obtained, as is done in a multicavity interference filter. However, because each stage is electrically tunable, the passband can be changed to any wavelength in the visible from 400 to 720 nm or also in the near-IR.

LCTFs are made of planar optical elements, which gives them a straight-through optical path. This geometry makes ...

... ranging from 1 to 3 in. long, and easy to integrate into a microscope. And they do not interfere with the optical system.

For example, in bright-field work, uniform "Koehler" illumination is not degraded. With most other types of monochromator systems, except filter wheels, the microscope must be customized in some way to accommodate their optical and mechanical configuration.

Second, their image quality is extremely high. The modulation transfer function of a 20-mm-diameter LCTF reaches zero contrast at a resolution of ...

... ms is adequate.

Throughput appears to be sufficient for most applications in bright-field and fluorescence. After taking into consideration transmission, acceptance angle and aperture size, LCTFs provide between one-quarter and one-third the flux that an interference filter with comparable bandwidth can provide. With LCTFs, angle of acceptance is defined as the angle at which the center wavelength shifts 10 percent of the bandwidth. The transmission is relatively uniform for rays ranging from normal incidence to the maximum acceptance angle. Also, for most applications ...

... high throughput for weak fluorescence signals.

For applications that place the LCTF in front of a lamp source, care must be taken to prevent the LCTF from getting too hot ((is greater than)50(degrees)C). Proper use of IR rejection filters and a heatsink enable the filter to be used with any of the arc or filament lamps that are commonly used on microscopes.

The most significant contribution of LCTF technology to spectroscopic imaging is its capability to convert any monochromatic camera into a multispectral camera. On the microscope, it can transmit spatial ...

... strongly on the ability to simultaneously resolve minute spatial detail and narrow bandwidths of light. As more probes are developed and systems become more complicated, automation, versatility, increased speed, convenience and dependability will become increasingly important. Solid-state and electro-optic monochromators, such as the AOTF and the LCTF, are well suited to this emerging field of spectroscopic imaging.

Lithium niobate is a unique material whose varied optoelectronic properties have found use in a wide variety of important applications, including surface acoustic wave devices (widely used in television sets), optical deflectors, tunable optical filters, laser modulators, Q-switches, and transducers. This material was first synthesized 25 years ago and has been the subject of numerous scientific and engineering studies ever since. It has a complicated crystal structure, which is responsible both for its unusual properties and for many of the difficulties in ...

... Kuz'minov (both of the U.S.S.R. Academy of Sciences) is very welcome indeed.

A range of topics is covered, including the physical and chemical properties of LiNbO sub.3 ; methods for making single crystals; defects; domain structure; optical inhomogeneities; and electrical, optical, electro-optical, nonlinear, photoelectric, and photorefractive properties. The subjects covered are treated in great depth for the most part, but the book is not fully comprehensive, as it leaves out the fields of integrated optics (in which LiNbO.sub.3 is an important substrate material), acousto-optic properties and applications, and related optical materials. This book is filled with interesting facts and information that will be of use to both materials and device researchers. Many of the known property data on LiNbO.sub.3 have been collected here, which makes this a useful reference book.

... ship, or truck and the numbers of platforms are not increasing. Therefore, the growth of SAW devices is limited.

A new application that displaces a different device opens up growth opportunities. Examples are low phase noise oscillators for MTI applications and airborne laser radars. The radar area is one of relatively low volume and high unit costs for SAW. A radar system is considered to have high volume if several thousand are manufactured over the life of the program, with annual rates of several hundred. An exception to this is ...

... types; it covers the spectrum from DC up through optical frequencies; its modes range from point-to-point through satellite broadcast; and its waveforms go from CW to pseudonoise.

SAW has made several penetrations into this market. One is in vestigial sideband (VSB) filters for satellite television links. Others are in oscillators for fiber-optic modems and data-retiming modules that use filters and oscillators.

This market has a potential for sizable volumes. VSB filters have been in production for 10 years, and the volume runs at the 1000 to 2000 per month level. Clock recovery module production began a few years ago. It is running at 2000 per month and will go ...

... cheap and disposable.

Navigation Equipment

A variety of navigation systems are potential users of SAW devices. All are based upon radio transmission, with frequencies ranging from below 10 kHz to several GHz. Applications on the higher frequency systems are for filters and oscillators, and possibly tapped delay lines and filter banks. Volumes can be large, as the numbers of users can be great. SAW devices are small, rugged, and highly reproducible, giving them a competitive advantage on moving platforms. The applications are straightforward and new systems are the preferred opportunity.

New SAW-Related Technologies

There are three types of technological shifts that will change the marketplace. The first is the evolution of present SAW methodologies for improved performance. Examples are lower loss filters and lower sidelobes on reflective array compressors. Production methods basically would be the same.

The second shift modifies the present technology to the point where new production methods are necessary, and perhaps new materials as well. In this class are surface-skimming bulk valves ( ...

Low Loss Filters

Work has been proceeding on low loss filters for at least 10 years. The current high insertion loss of SAW devices, typically 12 to 26 dB, even with matching devices, precludes their use in many applications. In this article, the 3+ dB range is called moderate ...

... performance levels. A key point is ease of design. If the design takes many iterations, the nonrecurring engineering charges will be high, and costs on short runs will be noncompetitive. Processing costs also must be kept low.

Several low loss filter designs probably will be available soon in configurations reasonably easy to create. Table 6 through 9 show the impact of various filter improvements on the potential market.

If moderate loss filters were available, sales would increase roughly by 50 percent. The number of low loss filters would probably double, even with a small price premium. This represents an increase of nearly $20 M. The communications market would more than double.

Filter Rejection and Rebound

Crystal filters and many LC filters produce 60 dB of relative rejection in production models. Typical prices for crystal filters at 70 MHz in quantities of 1000 range from $55 to $85 each. Most SAW devices today achieve frequency rejection levels in the 40 to 45 dB range in production; a few have reached 55 dB. ...

... layout of internal absorbers. Perhaps new materials are needed as well as some thought given to channelization of diffracted and reflected energy. This will have the secondary benefit of improved suppression of triple transit time energy.

A second undesirable effect with SAW bandpass filters is a decrease in frequency rejection at frequencies many bandwidth multiples away from the center of the passband, commonly referred to as rebound. In filter banks, this can be disastrous. Since this phenomenon is caused by uncontrolled secondary effects, such as internal reflections, it is not calculable. As in the rejection case above, more attention must be paid to designing for the control of out-of-band signals and meticulous process control in manufacturing. If these improvements are met, they could increase filter sales by 25 percent, largely at the expense of crystal filters.

Lower Loss Dispersive Devices

A few attempts have been made to reduce the insertion loss of dispersive filters and delay lines. The impact upon the marketplace will be relatively small, however, because such devices are seldom located in equipment circuits at a point where loss is important. At this time, one can only hazard an educated guess that such devices might be ...

... properties. What they get is rapidly escalating NRE charges coupled with low confidence of performance. These new methods can win and keep customer confidence.

The mechanization process will have an impact in the near future on more routine designs. Crystal filter NRE charges for a 70 MHz design range from $2500 to $8000, including samples. NRE charges for a similar SAW filter are twice that amount. The mechanization techniques could make the NRE charges comparable. The reduction of NRE charges can be critical when penetrating new markets.

Production processes are improving too. Every one of the suppliers has the capability of submicron line work. What is needed are enhancements in other ...

... finger dimensions is most important. This improvement already has been demonstrated with oscillators achieving 3 GHz in the fundamental mode. Prototype work is currently in process at several laboratories and at least one manufacturer.

MIMIC is in need of miniaturized filters and delay lines at microwave frequencies. These can even be piggybacked over the circuits. SSBW devices have slightly higher losses than SAW devices, but this may be tolerable. The impact of these items will be slow, and probably will not be in great use by 1991. They could be in use before then in microwave links, some radars, and satellite links. They might have an impact of 5 to 10 percent in filter sales by 1991. Over the long term, these miniaturized filters and delay lines could double sales.

ACT is a relatively new technology still under development. Electronic Decisions Inc., Urbana, IL, has a multiyear contract from the Defense Advanced Research Projects Agency (DARPA) to ...

... ZnO on Si, and on GaAs. The current work is being done on GaAs.

ACT can be used for the functions of storage, signal sampling and charge sensing. In addition, it can perform as a delay line, transversal filter and as a phase-coded correlator, as well as a wide range of other devices. The advantages for the user are greater dynamic range, high data rates and integration with semiconductor circuits.

ACT has delays limited to a few microseconds. However, its potential for ...

... economic considerations that determine the use of SAW devices and subsystems cannot be applied without understanding their role in this design.

Depending on dynamic range, it is being used at bandwidths of 3 to 40 MHz Conclusion: SAW will have a market segment for the forseeable future particularly where size and weight are important.

The analog signal processing methods that can be considered as SAW's competitors are acousto-optics, electro-optics, bulk acoustic waves and magnetostatic waves.

Acousto-Optics

Of the various pros and cons relating to acousto-optics the two major features that stand out are wide bandwidth and limited dynamic range. Much work has been done over the years to improve the dynamic range, but to little avail. Heterodyne techniques have helped, but all to date have proven highly nonlinear. ...

... spectrum analysis. A point to be noted is that SAW devices are integrated with A-O systems.

Bulk Acoustic Wave (BAW)

Devices

The use of BAW devices in signal processing is undergoing change as new modes become available.

Bulk acoustic resonators in high harmonic modes (HBAR) and in films (FBAR) have been made in laboratories and some are approaching practical applications. BAW devices employing diffraction gratings have been developed as well. While none of the above items is in production yet, they could offer competition to SAW; HBAR for oscillators, FBAR for filter banks at microwave frequencies and BAW diffraction gratings in spectrum analyzers.

HBAR devices have been operated in the 1 to 2 GHz frequency region as oscillators. They operate with low phase noise because of their high-Q values and their ability to operate at high fundamental frequencies. Current devices suffer from high insertion loss and severe temperature problems in the longitudinal mode. The shear mode is being investigated.

FBAR is used to create channelizers by means of an array of films. Experimental filters have been made with passbands centered as low as 400 MHz to a high of 8 GHz. At the higher frequencies, insertion loss has risen rapidly. However, they are small and would be cheap to produce.

These devices are still under evaluation and their drawbacks may yet prove too great. Even if they are successful; they will not be in production before 1990. HBAR may replace SAW oscillators above 1 GHz in the long term. FBAR may be useful for filters at frequencies above 2 GHz. Below these frequencies, cost will be the deterrent.

Electro-Optics

Electro-optical signal processing is used seldom in direct form, except for switches. It too suffers from dynamic range problems. Some ...

... high data rate applications, the requirements of the associated digital circuits in power, size and cost overshadow the savings from the analog circuits.

As higher speed devices are made, the digital circuitry moves forward up the signal path. This is obvious in channelized receivers. The rate that such movement occurs also is governed by environmental factors. For example, in one application where size, weight, power and ruggedness were not a significant factor, the user had 40 MHz channel bandwidths. In a similar application, but where ...

BODY:

... optics and electronics being integral, mutually compatible components of systems for consumer markets, industry, and defense. The basis of this progress is the development of materials that have the required purity, physical properties, and optical quality; glass fibers for optical transmission, semiconductors for lasers and detectors, and nonlinear materials for optical switching are examples. In this article, some of the materials of choice for a variety of applications are described and the frontiers of materials research for new areas of opportunity are discussed. Particular emphasis is placed on optical ...

... tubes, alphanumeric light-emitting diodes (LEDs) and liquid-crystal displays. In recent years, however, optics has been spreading more and more into areas that were traditionally the domain of electronics. This is most noticeable in communications, where an entire network of optical fibers, LEDs, lasers, and detectors has already been installed for transmission of voice and data. Optical disk recordings with semiconductor-laser playback are replacing the conventional piezoelectric pickup. Solar cells are now common components in toys, calculators, and other consumer electronics. Infrared detectors and lasers are the basis of many intrusion detection systems. There are numerous other examples.

The trend toward optical technologies will likely continue in consumer markets, industry, and defense systems. The development of materials with the necessary optical properties is the basis of each technology whether it be ultralow optical-loss fibers, semiconductor lasers emitting milliwatts of power, or gigawatt lasers for destroying missiles. The optics research community is now very diverse and the materials requirements are generally different for each application.

In Table 1, I list a number of optical technologies together with some examples of the materials of current interest. ...

... spacing. Present estimates place the acceptable power levels in fluoride fibers at about 1 mW. On the other hand, fiber materials having high cross section for these nonlinear effects may well find applications as parametric amplifiers, optical frequency converters, or optical pulse compressors.

Material dispersion is also another critical parameter for optical fiber technology. Because of the finite spectral line width of laser sources, a short optical pulse injected into the fiber is broadened by the dispersion during propagation, eventually leading to pulse overlap and errors in pulse discrimination. In silica, the wavelength of minimum dispersion occurs at [lambda] = 1.3 [mu]m, somewhat separated from the wavelength of minimum total loss (1.55 [mu]m). The effects of dispersion can be minimized by using narrow line width lasers. Alternatively, by careful design of the index profile of the fiber, fibers can be made in which material dispersion can be canceled at specific wavelengths by waveguide dispersion[7]. Theoretically, techniques of this kind can be applied to longer wavelengths and lower ...

... chalcogenide glasses [GeS.sub.2],[As.sub.2][Se.sub.3], and even polycrystalline thallium bromo-iodide (KRS5) and heavy metal (cadmium, cesium, and lead) halides are under active investigation for the delivery of [CO.sub.2] laser power in surgical[9] and robotic applications, or even for remote sensing of thermal images. Most of these are short fiber-length applications and ultralow loss is not required. Because of the simplicity and low cost of remote monitoring, sensing, and power transmission with fibers, we can anticipate expansion in this area of research.

Semiconductor Lasers and Detectors

Probably the largest effort in optical materials is currently being devoted to semiconductors because of their importance in light-emitting devices (lasers and LEDs), detectors, and microelectronics, as well as the hope of combining optical and electronic functions on the same chip. Although silicon is now the dominant material for electronics technology, it plays a relatively small role in optics. Silicon has an ...

... electrons is very different from that for holes and this leads to exceptionally low-noise detectors for high-bandwidth optical detection.

Group III-V semiconductors. For LEDs, it is necessary to use direct band-gap compound semiconductors. The first semiconductor laser ever fabricated was made from GaAs[10], which efficiently emits light near 0.88 Km in the near infrared. This material is still important for lasers and LEDs in consumer electronics. Since a strong parallel effort is under way to develop high-speed GaAs electronic integrated circuits, the dominance of GaAs optoelectronics is likely to continue for some time. However, since the optical loss of fibers ...

... wavelengths for long-distance communication. Some of these alloys have electronic properties superior to those of GaAs and may well find extensive application for high-speed electronics once the technology is fully developed.

In conventional technology, semiconductor structures for lasers and detectors are first deposited as thin films on a substrate of equivalent lattice parameter by means of techniques described in another article of this issue[11]. The material composition is determined first by the wavelength of operation and second by the choice of ...

... structures can be used for efficient far-infrared detection, in much the same way as intrinsically narrow band-gap semiconductors[13].

Group II-VI semiconductors. If III-V semiconductors have received the major share of attention for lasers and near-infrared detectors, II-VI semiconductors have received the major attention for far-infrared detection, particularly in the wavelength range from 5 to 10 [mu]m, which is of importance for night vision and thermal imaging.

... conduction) and n-type (electron conduction) material from the same composition for thermodynamic reasons. It requires less energy to create structural defects (that is, anion or cation vacancies) than to create free carriers in the conduction or valence bands. For injection lasers it is essential to have p-n junctions in order to excite fight emission with electric current. This is readily accomplished in GaAs by doping, and consequently this technology gained momentum.

Group II-VI materials have recently received increased attention because of the need for semiconductor lasers and LEDs that emit in the blue. Blue lasers would allow higher density data storage on video disks, and blue LEDs are useful for information display. With new low-temperature crystal growth procedures and novel multilayer structures, this area of research is likely to yield important new results.

...

... research in semiconductor materials is being carried out on those materials already discussed, many other semiconductor materials systems have received less attention or have even been ignored. Group IV-VI semiconductors such as PbTe and PbSnTe have been developed and are commercially available as lasers for the middle infrared. Figure 3 shows the optical band gap versus the lattice parameter[23] of the lead-tin chalcogenides. These materials have not shown promise for infrared detection because of the high-background free-carrier concentration associated with natural ...

... systems generally need some form of switching system to couple specific input channels to specific output channels. In optical communications, this can be accomplished with electronic switching systems by first detecting the optical signal and then converting back to optics with lasers after the switching functions are completed. This entire process can be simplified by directly switching the optical signals with electro-optic waveguide switches[27] fabricated in [LiNbO.sub.3].

If there is to be an optical computer of the future, it will have an architecture quite different from that of digital electronic computers. The goal of such a machine would be to take advantage of the ultrahigh speeds available with optics [laser pulses as short as 8 fsec have been measured[33]] or the high degree of parallelism and simple interconnection offered by optics. With existing materials, however, an energy of about 0.1 to 1 pj is still required for each switching event, which limits the data rate to [10.sup.12] to [10.sup.13] bits per second for a 1-W laser, regardless of whether serial or parallel processing architectures are used[34]. The achievement of both a high degree of parallelism and a high pulse throughput will require considerable advances in nonlinear optical materials. In the meantime it seems certain that ...

This is one of several factors prompting some EW companies to expand their technical and production capabilities via acquisitions. Loral, whose expertise originally was focused on radar warning receivers (RWRs), has gone further than any other company in the EW field to expand its capabilities through acquisition. Within the past several years, Loral moved into the increasingly important infrared countermeasures field, through its acquisition of the major portion of Xerox's Electro Optical Systems Div., Pasadena, Calif. The division, which is one of three major suppliers of infrared jammers to disrupt heat-seeking missiles, welcomed the acquisition, according to Jack Davis, who heads the operation, "because Loral talks and understands the EW business."

The division's expertise in acousto-optic transducers (known as Bragg Cells), originally developed for use in Xerox laser printers, is being advanced for possible use in Loral's mainstream radar/threat warning receiver business.

Loral Acquisitions

Additionally, Loral acquired Hycor, which produces chaff and infrared decoy-flares, principally for Navy ship protection, and Narda Microwave, a major supplier of microwave integrated circuits (MICs) and subassemblies. Recently, Loral acquired the ...

Litton Industries extended the scope of the EW capabilities of its Amecom Div. with the recent acquisition of Itek, which earlier had acquired Applied Technology -- a pioneer in radar/threat warning receivers.The acquisition of the parent Itek also produced expertise in acousto-optic transducers for application to radar/threat warning receivers, according to Charles Fink, vice president of Litton's Electronic Warfare Systems Group.

Additionally, several years ago Litton acquired International Laser Systems, Orlando, Fla., a major supplier of laser rangefinder/designator systems, in order to broaden the group's efforts into electrooptics.

First update kits is to be delivered this spring by Eaton's AIL Div., for installation by General Dynamics, Ft. Worth, after which system will be tested at Eglin AFB, Fla. Second phase, still tentative, would introduce new receiver-processors being developed by Litton Industries for use on Navy/Grumman EA-6B, which uses similar ALQ-99E jamming transmitters. Third phase, still under study, would install Raytheon/Sedco phased-array antenna systems to enable EF-111As to deliver higher jamming power against threat radars. Picture 2, Navy/Grumman EA-6B escort jammer also is being updated under Navy's AdvCap (advanced capability) program. New Litton Industries receiver-processors will use channelized receiver techniques to provide improved monitoring and analysis of threat signal characteristics for use of deception jamming techniques. First test of new receiver-processors is scheduled for 1988, with production targeted to begin in 1989. First production systems are expected to be installed in new Grumman Block 90 aircraft which are to enter service around 1992. Grumman is responsible for AdvCap integration which includes installation of new Eaton/AIL exciter-modulator for high-band transmitter.

In recent years there has been a resurgence of activity in optical information-processing devices which make use of effects such as optical bistability, photo-refractive effects and numerous electro-optical, acousto-optical, and all-optical processing schemes in integrated optics. In parallel, theoretical studies have been made of novel architectures for information processing which capitalize on the unique capabilities of optics.

Many important and nearer term applications of optics will involve the switching of light beams with externally applied fields in an electro-optic material or with sound waves in an acousto-optic material, but these are beyond the scope of this article.

These basic problems have not, of course, changed. However, there have been several developments of importance which have stimulated a new look at the role of optics in information processing.

1) Mode-looked lasers are now readily available which deliver optical pulses of subpicosecond duration--shorter than any electronic pulses available. Such short, intense pulses should permit subpicosecond switching operations.

2) New materials and new nonlinear mechanisms have been discovered which have larger optical nonlinearities.

... cavity, but with increased system complexity. It is also likely that adequate contrast can be achieved with phase changes considerably less than pi in many processing operations, thereby reducing the energy required per switching event. Thus, for a single injection laser source of is approx. 10 mW power, a bit rate of 10.sup.10 per second is achievable. To achieve 10.sup.12 bit per second, a laser diode array having 100 injection lasers is required. An important point here is that with simple optical sources, the available source power limits the simultaneous use of high speed and a high degree of parallelism. The material response time should be tailored to the requirements of the system: a material which is too fast does not make ...

... exciton nonlinearities in semiconductor multilayer structures are best suited to direct image processing. A potentially much wider range of applications exists in processing information that is transmitted serially down fibers and converted into parallel streams by means of laser arrays or liquid crystal light valve arrays. Such applications include numerical computation such as matrix algebra (12). This potential continues to provide the motivation for fundamental work in new materials and mechanisms for nonlinear optical processing.

HEADLINE: Navy Studies Photon Echo Memory Use

BODY:

... discussed in Soviet scientific literature during that period. As originally defined by the Columbia Radiation Laboratory scientists, a photon echo is a light pulse that is emitted spontaneously from a system of atoms previously irradiated by two coherent (laser-generated) resonant light pulses.

For the memory application, Advanced Technology uses a variant of the basic photon echo called the stimulated photon echo, which uses three optical pulses to produce the photon echo. The first two Pulses serve as the " ...

... medium, and the third acts as a "read" pulse to access the stored bit. This variant allows the memory refresh time to be extended to minutes while retaining nanosecond read and write times, Friedlander said.

The memory system comprises an array of diode lasers, a beam deflection subsystem, the echo or storage medium, and an array of semiconductor detectors. One laser and one detector form a pair that can store and retrieve one bit of information at a time.

The memory gains its essential advantage by storing information in an unstructured, three-dimensional medium, Friedlander said. It can pack information as densely in depth as in a plane. Since its planar packing density is comparable to that of other storage technologies, its total packing density consequently exceeds that of other technologies by a very sizable margin, he said.

The laser, addressing, logic, detector, power and mechanical subsystems and the storage medium needed for the photon echo memory all have been studied separately, and these studies demonstrated that the memory can be built from off-the-shelf components. However, a system engineering effort is needed to combine these ...

... demonstration of a working memory, Advanced Technology last month proposed construction of a very small memory -- with only 10-100 memory locations -- to the Office of Naval Research, primarily to demonstrate that information can be written into and read from the memory medium as predicted. The laser-based technology should be capable of on-line storage of 10<15> (1,000 trillion) bits of data in a 1-cu.-ft. volume and of providing nanosecond read, write and access times, according to Friedlander.

Ruby Laser

The original experiments at Columbia employed a ruby laser as a light source and a cooled sample of ruby as the echo medium, but other sources and storage media can be used. The photon echo phenomenon is a very general one and does not need special materials for its observation, Friedlander said. ...

... necessary optical lenses and electro-optical deflectors at the input and output of the storage medium.

Although the photon echo phenomenon is inherently three-dimensional, the proposed demonstrator would operate as a planar device to keep cost and complexity low.

Existing semiconductor laser and detector arrays are adequate for the development of the photon echo memory, and the broad market for these products should lead to further improvements in standard products that could be used in future memory systems without cost to the memory program.

For example, lasers having narrower pulsewidths and higher pulse repetition rates -- developed for communications sytems possibly -- would allow the development of photon echo memories with higher read and write speeds.

Detector array technology is considerably more advanced than laser array technology, providing up to 100,000 individual detectors on stock devices, with densities of 1,600 detectors per square millimeter. Standard laser arrays offer only 100 emitters or less per device, at densities of up to 64 lasers per square millimeter.

The addressing subsystem, which Friedlander calls the heart of the photon echo memory, will require the most development effort. Although the elements of the various alternative techniques being considered for this application have been demonstrated in the laboratory environment, they have not ...

... medium at differing angles and will incorporate more than one frequency to reduce background noise.

Addressing resolution of one part in 10<5>, required in each of the three axes of the storage medium, can be obtained using either electro-optic or acousto-optic beam deflection. The electro-optic approach is preferred because it can provide higher deflection speeds and requires less power, Friedlander said.

Two different deflection timing schemes will be used. Refresh timing can be accomplished with low-power sinusoidal scanning of the beams, and random- ...

... higher power but low duty cycle pulsed scanning.

The principal engineering challenges in developing a photon echo memory are expected to be met in the areas of refresh technique, addressing stability, and addressing resolution in the direction parallel to the laser beam -- the longitudinal axis of the storage medium.

'Relaxation Time'

The complete contents of a photon echo memory must be refreshed in less than the "relaxation time" of the storage medium -- approximately 5 min. for praesodymium-doped lanthanum trifluoride. A 10<15>-bit system employing 100 laser arrays of 100 lasers each thus would have to refresh stored data at the rate of 3 nanosec./bit. This is feasible with current technology, but the refresh timing is so critical to the retention of data that operational systems will have redundancy built into the system to allow for laser-detector pair failures. A microcomputer-based logic system will monitor laser-detector pair status and substitute backup pairs as needed. The refresh operation will become easier as the size of laser arrays increases, and considerable progress is expected in that area, according to Friedlander.

Intersecting laser beams defining a storage location within the echo medium must be returnable to any of 10<15> locations with an accuracy on the order of 0.1 micrometer. Off-the-shelf stabilization devices that are completely suitable for the memory application have produced ...

... stability can be achieved in an operational memory.

The key requirement in the intersecting-beam technique that will be used for longitudinal addressing is that the beam overlap region be on the order of one cubic micrometer. Operational systems used for laser surgery, welding, printing and other applications regularly achieve such tight focusing, Friedlander said.

Friedlander said the photon echo memory could be used in the development of an all-optical computer, which could yield advantages in weight, power requirements and ease of ...

Storage density will be limited by the minimum spot size obtainable with the wavelength of light used, the accuracy with which the light spot can be positioned in the storage medium, and the number of resonant atoms within the spot. In this concept drawing, a laser is the source of the photons that excite the echo in the storage medium, and the laser output is gated into pulses by the modulator. The X-Y deflector directs the pulses to a particular point on the face of the medium, and the Z-select mechanism -- considered the key feature of the memory -- selects the third coordinate to be addressed within the memory volume.
