CONTROL OF MUTUAL SPATIAL COHERENCE OF TEMPORAL FEATURES BY REFLEXIVEPHOTOREFRACTIVE COUPLING

We analyze reflexive photorefractive coupling of an information-bearin g beam carrying several distinct spatiotemporal features, with emphasi s on the coupling-induced change in the mutual spatial coherence. We f ormulate equations describing evolution of the mutual correlation func tions between different features and discuss their solutions both in t he full two-dimensional case and in the Limit leading to a one-dimensi onal description of the reflexive coupling geometry.
