Smart Pixels for Optical Processing

Abstract

This work explored the integration of optoelectronic components with traditional electronic GaAs device technologies. The goal was to realize highly functional optoelectronic integrated circuits (OEICs). The intent is to use OEICs to increase performance for demanding military applications such as wideband interconnects, computing, neural networks, pattern recognition, and communications. This program consisted of three phases of work. First Heterojunction Bipolar Transistors (HBTs) were integrated with Vertical-Cavity Surface Emitting Lasers (VCELS). Devices were successfully fabricated and demonstrated. Second, improved HBT/VCSEL devices were designed and fabricated. Third, PIN detector diodes were integrated with VCSELs for application as an optical interconnect element or as an optical processing element (smart pixel). A 2 x 16 VCSEL/PIN array was fabricated and characterized. Recommendations for device improvements and future work are provided.
