InGaAsP/InP Multiple-Quantum-Well Integrated Heterodyne Receiver.

We describe the fabrication and performance of the first integrated heterodyne receiver capable of actual heterodyne data reception. Integrating a continuously tunable 1.5microns MQW-DBR laser with a single-mode directional coupler/switch and zero-bias MQW waveguide photodetectors, we have achieved error-free reception of FSK-modulated pseudo-random digital code at 105 Mb/s.
