STORAGE OF HOLOGRAMS IN A FERROELECTRIC-PHOTOCONDUCTOR DEVICE

Abstract
Optical holographic storage and pattern storage have been demonstrated in an integrated ferroelectric‐photoconductor device (Bi4Ti3O12–ZnSe). The device has nondestructive readout and is erasable. Gratings as fine as 1.26μ were stored. Recording sensitivity was approximately 10μJ/mm2. Diffraction readout efficiencies of approximately 0.01% were measured.
