Abstract
Photorefractive crystal waveguide(PCW) is a novel approach to enhance the photorefractive effects.1-4 The waveguide geometry provides a tight optical field confinement and long interaction length of waves, resulting in increasing diffraction efficiency and angular sensitivity of hologram. It also allows to synthesize a high-density matrix array. Key issues to gain the practical applicability are how to overcome the drawbacks of PCW such as the finite aperture and modal phase dispersion which affects both image fidelity and holographic storage capacity.
