Generalized recursive network: a new architecture for self-routing non-blocking optical switch networks

In this paper we present a new approach for building non-blocking optical MINs on building blocks of given size. The network constructed by our approach is self-routing and has Oðlog2 NÞ propagation delay for size N N . The maximum signal loss and crosstalk are compared to those of the widely used crossbar network with the switch complexity of OðN Þ. The proposed approach is a good choice for constructing non-blocking optical switch networks with low signal loss and crosstalk. 2002 Elsevier Science B.V. All rights reserved.
