Abstract

This paper is concerned with the anplication of ontics to digital comnutina. We use a Huahes Liquid Crystal Liaht Valve (LCLV) as an active ontical element where a weak light beam can he used to control a strona liaht beam with either a Positive or negative gain characteristic. With this device as the central element we have demonstrated the ability to produce all the binary logic gates and to produce bistable states (flin-floos) which can themselves he used as logic gates or as memory elements. The aates and flip-flons have been used in the desian of ontical equivalents to a few simple sequential circuits such as shift registers and accumulators. These circuits then have tvnical annlication as a binary ontical integrator. The desians will he discussed and exneriments showing the limitations of the LCLV for this work will he presented. A brief discussion of coding theory as annlied to ontical computing will also be given.
