Loss 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 and eliminates all interconnection lines and crossovers significantly, but also reduces the number of drivers from N-2/4+2Nlog(2)N-2N to 2Nlog(2)N. After modifying the structures of the holographic optical switches to satisfy the characteristics of the double-layer network, the system insertion loss can also be significantly minimized and the required components can be reduced.
