Paper Abstract

Based on the electro-optic and piezoelectric effects, principle of a 2×2 bypass-exchange switch in photorefractive LiNbO3 crystal is discussed. In photorefractive volume grating, the Bragg condition can be deviated by applying a specific field during readout. That is, by applying a specific field Es or zero field, the diffraction efficiency will be 0 or 1, and this property can be used to realize the exchange or bypass operation of the switch. In this paper, on considering both the piezoelectric and the electro-optic effects caused by the applied electric field, we analyzed relations of both the specific field and the incident intensity ratio with respect to the writing angles and polarizations of writing beams.
