Tribute to Emil Wolf : science and engineering legacy of physical optics by Tomasz P Jannson( )

10 editions published between 2001 and 2005 in English and Undetermined and held by 143 WorldCat member libraries worldwide

An icon in the world of optics, Emil Wolf laid the foundations of contemporary physical optics by documenting the concept of spatial coherence before lasers were introduced. This powerful concept has influenced many areas of optical science and engineering, several of which are discussed in this book and are intended to pay homage to one of the great minds of physical optics. The material is presented by major experts in the field, many of them closely connected to Emil Wolf's Institute of Optics at University of Rochester

A Microprism Array for Large-Scale. Wide-Band Interconnection of Optoelectronic Systems( )

1 edition published in 1995 in English and held by 1 WorldCat member library worldwide

In this program, Physical Optics Corporation (POC) proposed to develop an optical communication/switching system with data speeds well beyond any state-of-the-art electronic board-to-board computer interconnect. This interconnect is based on the use of microprism arrays to achieve large-scale, wideband interconnections for optoelectronic systems. The main problem studied in this Phase II program was the current limitations of purely electronic interconnects, such as wide interconnection time bandwidths, large clock skew, and large RC time constants. These limitations cause serious bottlenecks in even the most advanced electronic board-to-board interconnects. This report presents the results of POC's investigation, and the implementation of the proposed microprism array-based optoelectronic system in this Phase II program. In Phase II, the major accomplishments of the investigation and implementation were: (1) Design of microprism arrays and electronic transceiver modules for the proposed optoelectronic interconnect system; (2) Design of the optical interconnect system; (3) Design, prototyping, and optimization of the transceiver modules; (4) Design of the bidirectional optical backplane bus architecture; (5) Optimization of the 5-channel optical backplane bus; (6) Implementation and demonstration of a 3x3 microprism-based optoelectronic crossbar interconnect system
Low Threshold All-Optical Crossbar Switch on GaAs-GaAlAs Channel Waveguide Arrays( )

1 edition published in 1994 in English and held by 1 WorldCat member library worldwide

During the Phase II project entitled 'Low Threshold All-Optical Crossbar Switch on GaAs - GaAlAs Channel Waveguide Array, ' Physical Optics Corporation (POC) developed the basic principles for the fabrication of all-optical crossbar switches. Based on this development. POC fabricated a 2 x 2 GaAs/GaAlAs switch that changes the direction of incident light with minimum insertion loss and nonlinear distortion. This unique technology can be used in both analog and digital networks. The applications of this technology are widespread. Because the all-optical network does not have any speed limitations (RC time constant), POC's approach will be beneficial to SONET networks, phased array radar networks, very high speed oscilloscopes, all-optical networks, IR countermeasure systems, BER equipment, and the fast growing video conferencing network market. The novel all-optical crossbar switch developed in this program will solve interconnect problems. and will be a key component in the widely proposed all-optical 200 Gb/s SONET/ATM networks. jg

Low Threshold All-Optical Crossbar Switch on GaAs-GaA/As Channel Waveguide Array( )

1 edition published in 1993 in English and held by 1 WorldCat member library worldwide

POC has proposed a 10 x 10 all-optical crossbar switch based on an optically activated modulator. A laser beam with an energy higher than the bandgap of the GaAs switches the propagation direction of the guided beam. Strong index modulation (>2%) can be induced by this method, which is not dependent on polarization for the EO effect. Both TE and TM guided waves have the same induced index change. Because there, am no electrical contacts, this all-optical switch has no RC time limits. The switching speed is limited only by the generated carrier lifetime, which is in the picosecond range. Being the basic building block for high-speed optoelectronic computing and signal processing, this generic concept is applicable to a broad variety of photonic components, including optical logic gates, EO modulators, variable delay lines, and crossbar reconfigurable interconnects. To optimize the switching efficiency, several optical switch designs were studied, including cross switches and directional coupler switches. To realize the multichannel optical switches, a compact self-aligned packaging technique was developed. An all-optical switch using a 0.8 micrometer pumping laser beam and a 1.3 micrometer probe beam has been demonstrated, and efficiency as a function of pumping power and wavelength was studied.

Polymer Based All-Optic Reconfigurable Interconnects( Book )

1 edition published in 1994 in English and held by 1 WorldCat member library worldwide

In Phase I of this project, POC successfully implemented a prototype all-optic reconfigurable polymer-based crossbar switch. POC's all-optic reconfigurable polymer-based crossbar switch represents a unique combination of polymer techniques, simple geometry optics, and waveguide technology. These three essential technologies are original POC developments. POC's crossbar switch will provide reconfigurability, large fan-out, and radiation hardening. This is a new technology for both parallel and distributed processing and communication networks. The Phase I results have shown that POC's crossbar switch can offer a number of important advantages not achievable by either electronic interconnects or currently existing all-optic reconfigurable interconnects. These advantages include: (1) very low power sources ( -100 mW), (2) relatively high interconnect reconfigurability time, (3) high data rates over 1 Gb/sec, (4) low bit error rate (<10- 10), (5) very large fan-out capability (<1000 channels), (6) very low manufacturing cost, and (7) very high erasability. It is expected that POC's crossbar switch performance will be superior to existing electronic and optical interconnection approaches. In Phase 1, POC also demonstrated the feasibility of commercialization in the area of multimedia, video conferencing, and other communication applications.
