Dedicated Optoelectronic Stochastic Parallel Processor for Real-Time Image Processing: Motion-Detection Demonstration and Design of a Hybrid Complementary-Metal-Oxide Semiconductor- Self-Electro-Optic-Device-Based Prototype

Abstract : We report experimental results and performance analysis of a dedicated optoelectronic processor that implements stochastic optimization-based image-processing tasks in real time. We first show experimental results using a proof-of-principle-prototype demonstrator based on standard silicon-complementary-metal-oxide-semiconductor (CMOS) technology and liquid-crystal spatial light modulators. We then elaborate on the advantages of using a hybrid CMOS-self-electro-optic-device-based smart-pixel array to monolithically integrate photodetectors and modulators on the same chip, providing compact, high-bandwidth intrachip optoelectronic interconnects. We have modeled the operation of the monolithic processor, clearly showing system-performance improvement.
