Abstract

Holographic polymer-dispersed liquid-crystal (HPDLC) memory using liquid-crystal composites is proposed for new optical information processing. Formation of HPDLC memory using a photomask is discussed for parallel programmability to realize fast reconfiguration of optically reconfigurable gate arrays (ORGAs). The defect tolerance of HPDLC memory is investigated to clarify the defect limitation of holographic configurations using ORGAs. Experimental results show that the noise ratio less than 15% applied to HPDLC memory rarely affects its diffraction pattern or a reconfiguration context.
