Abstract

A new configuration of holographic switches is proposed and verified for multichannel optical switching. Experimental 1 × 64 and 2 × 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.
