Abstract

An optoelectronic switching technology based on the monolithic integration of arrays of binary optical switch nodes containing vertical-cavity surface-emitting lasers (VCSELs) and heterojunction phototransistors (HPTs) has been developed. It can be used in multi-stage optical switching networks, and provides a reconfigurable 2D architecture for parallel optical interconnections. The VCSELs can also be integrated with heterojunction bipolar transistor (HBT) technology on the same wafer to provide a high speed optoelectronic interface between the optical switch fabric and the external electronic processing elements. Since these switches can be optically or electrically addressed and detected, they permit the direct communication and transmission of data between distributed electronic processors through a reconfigurable optical switching fabric and optical data link. The experimental demonstration of integrated photonic HPT/VCSEL routing switches and optoelectronic HBT/VCSEL switches that combine GaAs/AlGaAs VCSELs with HPTs and HBTs, respectively, are described below.
