Free Space Optical Memory Based on Vertical Cavity Surface Emitting Lasers and Self-Electro-Optic Effect Devices.

Abstract

A demonstration of a cascaded optical logic system in which an array of individually addressable vertical cavity surface emitting lasers (VCSELs) selectively controls an array of symmetric self-electro-optical effect devices (S-SEEDs) is reported. The VCSELs supplement a spot array generator that is used in other free space optical parallel processing systems of this type and enable a compact method of cascading S-SEED and potentially other smart pixel devices on a single array instead of cascading elements on many sequential arrays. Both a simple optical memory latch and an experimental scroll memory utilizing this approach are presented. (MM)
