Abstract:

This program began with the objective of developing a novel two dimensional optical smart pixel technology that would offer the potential for achieving very- compact, very high information throughput, parallel optical data processing architectures. The technology we had chosen was based on the monolithic integration of vertical-cavity surface-emitting lasers VCSELs with other photonic and electronic technologies. We played a leading role in the development of monolithic optoelectronic integrated circuit OEIC technology based on VCSELs, including heterojunction photo transistors HPTs and photothyristors PNPNs, PIN and MSM photodiodes, resonance-enhanced photodetectors, and heterojunction bipolar transistor MBT technology. During the course of developing these technologies, we also played a role in advancing the state-of-the-art in- VCSEL technology, which was then in 1991 in a nascent phase of development. Our major contribution to VCSEL technology occurred in 1991, when we became the first group in the world to achieve a significant improvement in the electrical characteristics of VCSELs by the continuous compositional grading of the heterointerfaces using MOCVD growth. This early impetus allowed us to achieve many different high-performance optoelectronic devices based on VCSELs, including several families of optical switches with latching, non-latching, and bistable characteristics 1991, monolithic optical logic gates 1992, reconfigurable optical routing switches 1993, programmable optical logic gates 1994, high- speed optical transceivers 1995, an optically cascaded multi-stage switching fabric 1995, and a cascadable programmable optical logic gate array 1995. Amongst our other contributions to VCSEL technology included the development of high-performance cryogenic VCSELs 1994 and cryogenic optical data links 1995, and the use of
