Abstract

A high-speed monolithic optical interface switch LSI is developed using a GaAs MSM photodetector and large-scale integrated electric circuits. This LSI operates universally as a 1.8-Gb/s optical-input/optical-output four-channel time-division switch, a 1.8-Gb/s optical-input/electrical-output 1:4 demultiplexer, a 2.0-Gb/s electrical-output 4:1 multiplexer, and a 2.8-Gb/s electrical-input/electrical-output 4 × 4 space-division switch. It uses a new multistage 2 × 2 switch block with small hardware and high-speed operation. It can be expanded to a 16 × 16 optical-input/optical-output time-division switch operating at up to 1.8 Gb/s for broadband-ISDN.
