Monolithic Optoelectronic Circuits For High-Speed Optical Interconnects

We report on the status of a monolithically integrated transceiver chip being developed in our lab. The functional components of this chip consist of a TJS laser, a photodetector, an amplifier, a 4:1 multiplexer, a 1:4 demultiplexer, and a gate-array. The total gate count is -500, and the chip is designed for operation at 1.0 Gbps. The receiver section of the chip has been tested with optical inputs at a 1.0-GHz clock frequency. Fabrication of the entire transceiver chip is in progress.
