Paper Abstract

Requirements of advanced generations of computers and signal processors dictate not only high computational speed, but highly parallel architectures. These highly parallel systems require significant communication at gigabit data rates with high fanout capabilities. These systems also require multiple switching of high rate data paths to cilitate efficient functioning of parallel architectures. To realize these requirements, MSI level GaAs optoelectronic integrated circuits have been developed to overcome the limitations associated with conventional electrical interconnections. Digital GaAs circuits have been integrated with optoelectronic laser transmitters and detectors to achieve high speed, high bandwidth, optoelectronic ICs for chip level and board level optical data communications. More recently these chips are being interfaced high speed VLSI silicon ICs to form optical fiber crossbar switches, under the sponsorship of DARPA/NOSC. These circuits are expected to operate with data rates of 250 MHz and reconfiguration times of 1 nanosecond. Optical fiber crossbar switches up to 32 X 32 arrays are planned.
