Holographic memory formed by multi-context recording for optically reconfigurable gate array

A holographic polymer-dispersed liquid crystal (HPDLC) memory formed by volume gratings is fabricated to record multi-context information based on the various circuit contexts. The contexts are recorded at various separated regions in the HPDLC memory by connecting a rotating pinhole set on a glass cell filled with LC composites and a metal photo mask written by the multi-context patterns placed on the motorized X-stage under the control of a personal computer. The HPDLC memory presents clearly reconstructed multi-context images composed of various circuit contexts.
