Acousto-Optic Interactions.

Abstract

New devices are described which are based on optical waveguides on lithium niobate crystals, using the material anisotropy, including couplers, electro-optic modulator and light multiplexer, and optical deflector and scanner using collinear acousto-optic interaction between surface acoustic waves and optical surface waves. Complete theory for the propagating modes and coupled modes is presented. A new type of waveguide is presented for use with surface acoustic wave devices for real-time direct scanning and Fourier transform scanning of optical images, which introduces no additional transmission loss over that for unguided propagation. Test pattern results demonstrate the ability of this type of waveguiding to increase the transverse resolution of such scanners, and good correlation between theoretical and experimental results is shown.
