Implementation of N×N cross-bars using RNI devices

In this paper we propose to implement the N×N crossbar using Reversible Nonlinear Interface (RNI) devices. The basic characteristics of optics such as higher bandwidth, flexible interconnections, and their application to parallel processing hardware and software contribute to the development of a very efficient optical computer. Optical implementation of various kinds of computing gates has been difficult in the past. In some cases, a gate can be implemented, but the output power from the gate is so low that cascading these gates into useful optical computing elements is impossible. RNI devices can be easily integrated
