Abstract

Optical matrix processors were developed to exploit the high degree of parallel connectivity inherent in free space optical interconnection. Researchers have proposed and investigated optical algebra processors for at least three decades^1,2. Recent advances in multi-channel modulators’ vertical cavity surface emitting laser (VCSEL) diode arrays, light valve technology, and detectors have potential to make these systems practical for many applications. Specifically, vector-matrix processing can give much higher throughput than digital approaches and many applications exist were performance can be bought with speed even at the price of accuracy or dynamic range^3,4.
