Abstract

Basing on the vectorial theory of light diffraction in photorefractive crystals of cubic symmetry, we derived analytical expressions that describe the outgoing intensity of coherent beams coupled with the dynamic grating and subjected to a fast phase modulation. It is shown that the linear transformation of fast phase excursions into intensity modulation is achieved in crystals with non-local photorefractive response after a proper polarization filtering of the transmitted beams when an alternating external field is applied to the crystal. Theoretical results are supported by the experiments with Bi12TiO20 crystals of various optical configurations.
