Abstract

The objective of this paper is to motivate a new class ofdigital logic. OptiComp has focused on a digital optical logic family in order to capitalize on theinherent benefits of optical computing which include: Attribute #1: High FAN-IN and FAN-OUT Attribute #2: Low power consumption Attribute #3: High noise margin Attribute #4: High algorithmic efficiency using "Smart" interconnects Attribute #5: Free space leverage of GIBP (gate interconnect bandwidth product) Other well known secondary advantages of optical logic include (but are not limited to): Zero capacitive loading of signals at a detector Zero cross-talk between signals Zero signal dispersion Minimal clock skew (a few picoseconds or less in an imaging system) The primary focus ofthispaper wiibe to demonstrate how each ofthe five advantages can be used toleverage other logic family performance such as GaAs; the secondary attributes will be discussed only in the context of introducing the DOC III architecture.
