Abstract

A logic memory cell is provided consisting of a set/reset flip-flop having input and output light pulse signals connecting through fiberoptic waveguides. The device uses a combination of optical and electrical positive feedback to maintain the switchable bistable output states Q and (Q). The electro-optical gate used in this device is a liquid crystal (L-C) cell using the dynamic scattering effect.
