Paper Abstract

Compact holographic memory architecture with phase conjugate readout and diffraction suppression by internal reflection is investigated. The pixel size requirement for a competitive system is determined. The bandwidth of the holographic recording in LiNbO3 is broad enough to support the pixel size requirement by theoretical calculation and experimental measurement. Holograms of 1 micrometers 2 pixel size binary data are recorded and reconstructed with this system. The pixel size limit, signal noise ratio and the storage density for holographic recording in photorefractive crystals are discussed.
