Components Reduction of Double-Layer Networks with Holographic Optical Switches

Abstract

Combining the unique features of the double-layer network and holographic optical switches not only reduces the volume of the whole system, eliminates all interconnection lines and crossovers significantly, reduces the number of drivers from N-2/4+2Nlog(2)N-2N to 2Nlog(2)N, but also the system insertion loss can also be minimized. After rearranging the channels allocation, the number of electro-optic halfwave plates can be significantly decreased from 2N(2)-2N to 2Nlog(2)N.
