Abstract

We propose a novel technique for recirculating implementation of optical Banyan (butterfly) interconnection networks. The key concept is that two-dimensional segmental input/output patterns, rather than the conventional one-dimensional ones, are employed. This arrangement ensures that the two channels in a switching pair are always located at adjacent positions, which then leads to an efficient selection between the straight and the Banyan connection. As Banyan networks do not possess identical cascade stages, special rearrangement of the output channels is required in each stage so as to satisfy the requirement of recirculating implementation. This can be achieved by hybrid optoelectronic or all-optical means. If reconfigurable spatial light modulators are used, multistage Banyan networks can be realized by a single-stage optical set-up in a recirculating manner. © 1998 Elsevier Science B.V.
