Contactless Optoelectronic Integrated Circuits for Remote Fiber Optic Communication and Sensing Applications
Abstract
In this program, we introduced several new concepts which are directed at considerably reducing the complexity of existing optoelectronic integrated circuits (OEICs) and their associated systems by providing 100% of the power requirements of the circuits located at the remote node from the near- end terminal using optical means. In particular, remote powering via the use of monolithically integrated photovoltaic (PV) cells associated with each circuit was demonstrated in the In0.53Ga0.47As/InP materials system. A novel optical logic circuit which could be optically configured to operate variously as an amplifier, bistable switch, latching switch, S-R flip flop or an inverter was used as the focus of this demonstration. Furthermore, very high sensitivity, novel heterojunction phototransistors were demonstrated for use in high sensitivity, low power applications which typify optically powered circuits. It is expected that providing local, contactless power using PV cells monolithically integrated onto the functional OEIC chip can be used to advantage in highly complex, high density optical interconnect and optical computing systems. The study of these latter applications was a central feature of a broader program which we are now pursuing at Princeton University.
