Angular and speckle multiplexing of photorefractive holograms by use of fiber speckle patterns

Abstract

The scheme of using fiber speckle patterns can be applied to the multiplexing of photorefractive holograms. Fiber speckle referencing enhances the angular selectivity of the holograms. Speckle multiplexing is also possible by use of a mode scrambler. Also studied is the feasibility of a hybrid scheme involving simultaneous shift and speckle multiplexing.
