Dynamic photorefractive optical memory.
We investigate an architectural approach to dynamic three-dimensional volume storage that circulates holograms between two photorefractive crystals. Introduction of an optical amplifier into the system increases the effective write-erase asymmetry of the crystals and permits the amplification of the recalled images. This memory architecture is experimentally shown to provide write-erase storage with robustness to multiple optical readouts.
