Discrete correlation processor (DCP) as a building core of a digital optical computing system: architecture and optoelectronic embodiment

摘要

Digital optical computing is a promising technological field because of the excellent features of light for information processing, e.g., huge parallelism, high-speed, and large communication capability. Recently, great progress in the researches on the smart pixels enables us to design various kinds of optoelectronic devices with very wide communication bandwidth. However, from the point of the view of optical application, the current optical interconnection demonstrators based on smart pixels utilize optical techniques just for simple data link, and they do not make best use of unique features of light. Thus, there is a question whether such optical data link will keep advantage over electronic counterparts when wafer scale integration and stacked structure of thinned VLSI chips become accessible.
