Abstract

In the paraelectric phase photorefractive crystal, the quadratic electro-optic effect can result in Bragg gratings in the volume of the crystal. The reconstruction process and the diffractive properties of the grating can be governed by the externally applied electric field. The measurement of the diffraction efficiency as a function of the applied electric field during recording is described. Dependence of electrically controlled Bragg grating in paraelectric phase KLTN: Cu crystals on readout illumination beam polarization were experimentally investigated. The results of experiments show that the diffraction efficiency of electric-controlled volume grating can also be controlled by the polarization of readout light. All these results would offer an possibility for a photorefractive optical switch by adjusting the polarization of the readout beam to control the diffraction efficiency.
