Abstract

This paper addresses the concept of active optical processing, in which signals are processed due to a nonlinear transfer function (light output as a function of light input). The particular active device considered here is a bistable optical device (BOD), which typically has transfer curves such as those shown in Fig. 1. Devices whici have transfer functions such as these can be used fc,-- signal enhancement, optical logic, memories, and switching. The aim of developing active optical processing is to achieve high speed all-optical operation, which is not limited by electron transit time considerations. An all-optical processor should have psec response times. In addition, the all-optical nature means freedom from emi, rfi, cross-talk and security, which are also characteristics of optical fibers.
