An array of optical Fredkin gates implemented by optically controlled waveguide couplers is shown to constitute a very efficient and versatile optical interconnection network with parallel addressing capabilities. The characteristics of the array are analyzed using linear algebra to indicate interconnect programming procedures. In terms of SNR this network is estimated to be comparable with previously proposed architectures. However, from many other aspects (light transmission efficiency, number of switching elements, speed, and fault tolerance) it has significant advantages.
