Abstract :
An N*N self-routing planar network suitable for fabricating optical space switches on lithium niobate substrate is presented. The network has O(N2) cross points, good modularity and expandability. It also has no waveguide crossovers and no differential attenuation between any of the input and output pairs. A self-routing control can be applied to this network, which is indispensable for ATM switching systems.
