ABSTRACT:
An optoelectronic device comprises a detector, an emitter and a modulator corporated into a single semiconductor chip. The optoelectronic device provides electrical isolation and optical interconnection (via waveguides) of the components of the semiconductor chip. Contacts for providing forward and reverse bias voltages are included in the device. The optoelectronic device is fabricated by growing a strained-layer quantum diode structure to produce a piezoelectric field in a quantum well, electrically isolating portions of the structure, and optically interconnecting portions of the structure. The fabrication is carried out by using an implant process or an etching process, and without having to use either regrowth techniques or packaging together of multiple optical elements.
