Diffraction of light by acoustic waves

Abstract

A method for calculating the intensity of diffracted light by acoustic waves is suggested in the present paper. The solution is obtained as an infinite vector, whose components define the light distribution into different diffraction orders, after the interaction of light with surface or volume acoustic waves. When the acousto-optical interaction takes place in a planar multimode waveguide the solution is given by an infinite matrix with components defining the light distribution both into different diffraction orders and light modes. An additional benefit of the obtained solution is its validity for all regimes of diffraction.
