Abstract

An innovative architecture for compact, integrated volume holographic memories is described. It is based on phase-conjugate readout and on a modulator–detector–memory array implemented in a silicon integrated circuit. The lensless memory module sustains dynamic read–write holograms by periodic refreshing. The integrated circuit is described and experimentally characterized. Holograms were stored in a prototype storage module that uses a 30°-cut BaTiO3 crystal and the 90° recording geometry. As many as three angularly multiplexed holograms were periodically refreshed and subjected to >40% decay from exposure to the reference beam over 50 to 100 cycles. Experimental data are presented.
