Abstract

In this paper we present an all-optical network architecture and a nearly-all-optical router for it. The sparse optical torus network consists of an torus, where processors are deployed diagonally. Addresses of packets are encoded and recognized by using fiber Bragg grating arrays. The optical address recognition ensures that only a few logical gates are needed to implement routing decisions at the routing nodes. A work-optimal routing of -relation is achieved with a reasonable size of .
