Paper Abstract

N X N Multistage Interconnection Networks are generally constituted by arrays of 2 X 2 switches linked together by some types of 'shuffle networks'. The number of stages necessary to obtain all the possible input-output links, is proportional to log2N. This number limits the dimensions of optical networks implemented on LiNbO3 crystals, because the length of the electrooptic switching elements cannot be reduced under a few millimeters. In order to link a number of users more than 8, a different architecture must be used. It is composed of (alpha) X (beta) switching elements with (alpha) equals 2(nu ) and (beta) equals 2(mu ) with (mu) does not equal (nu) . This reduces the overall network length by lowering the number of stages, even if the transversal dimension is slightly increased. In the paper the architecture of such a shuffle network is presented and its performance, in terms of networks power loss and crosstalk, is evaluated.
