Optical interconnects for use in high speed computing and communication systems require dense optoelectronic integrated circuits (OEICs). Monolithic integration of 111-V optoelectronics with VLSI-complexity electronics will yield OEICs of the high density, performance, manufacturability, and reliability. The Epitaxy-on-Electronics (EoE) technique monolithically integrates optoelectronic devices with commercially-fabricated, fully-metallized GaAs VLSI integrated circuits. This manuscript reviews the EoE process and details the fabrication of integrated LEDs. This LED-OEIC process is being used by optical interconnect systems researchers on a prototype basis through the OPTOCHIP project; the current status of this effort is reviewed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
