摘要

Features of Bragg diffraction of light by two-partial surface ultrasonic waves in planar gyrotropic optical waveguides placed in an external electric field are considered. General expressions for complex vector amplitudes of diffracted fields are presented. It is shown that the diffracted waves have elliptic polarization, the ellipticity being determined by the linear anisotropy of the waveguide structure, the anisotropy induced by an external electric field, the anisotropy of photoelasticity, and the crystal gyrotropy.
