Paper Abstract

The Banyan network belongs to the class of log, (N) stage networks like the perfect shuffle and the crossover networks. In our paper, an optical scheme for constructing the Banyan network in one single -block of photorefractive LiNbO, crystal is suggested. The photorefractive crystal is used to record layered holograms according to the structure of link stage of the network and repeatedly pulsed CO, laser beam is suggested to thermally fix the local layer holograms. Programmable electro -optic modulator array is selected as switches to implement the dynamic space- variant interconnect and the reflective elements as the cascading medium to implement the Banyan network in one single block LiNbO, crystal. Because the whole network can be implemented with one single block crystal and simple reflective elements, it has the properties of compactness and miniaturization.
