Experiments on a multichannel holographic optical switch with the use of a liquid-crystal display

Abstract

A new configuration of holographic switches is proposed and verified for multichannel optical switching. Experimental 1 x 64 and 2 x 32 switching is achieved by using real-time binary phase-only holograms generated by a twisted nematic liquid-crystal display. This holographic free-space switching is applicable to photonic switching systems and optical interconnections.
