Monolithic Optoelectronic Receiver for Gbit Operation

A monolithic optoelectronic receiver chip was designed and fabricated for operation at 1.0 Gbit/sec data transmission rate. The major components of the receiver chip are a fast photodiode, a preamplifier, and a 1:4 demultiplexer circuit fabricated on semi-insulating GaAs substrate. Optical/electrical functionality has been demonstrated at wafer level.
