Abstract

A novel architecture based on free-space optics is proposed for optoelectronic parallel computing systems. The main feature of the proposed architecture is its use of the optical image crossbar switch, a free-space optical switch that can directly switch images (two-dimensional optical signals) without any parallel-to-serial conversion. To demonstrate the processing capability of the architecture, I investigate a fully parallel matrix multiplication algorithm for the proposed architecture.
