Abstract :
The crossover network is introduced as a novel type of interconnection network for applications in optical digital computing, optical switching, and signal processing. It is isomorphic to other log 2(N) networks such as the perfect shuffle and the Banyan network. This means that algorithms which are based on the Banyan, such as FFT (fast Fourier transform) algorithms, can be translated to a crossover-based implementation. Using free-space optics it is possible to implement as many as 128×128 connections between two chips of optical logic devices. A setup for the implementation of crossover networks is proposed and demonstrated
