Abstract

Acousto-optic (AO) interaction in waveguide structures based on GaAlAs solid alloys has been investigated. A full set of the elastic and photoelastic constants of Ga_1-xAl_xAs was estimated. Dependencies of the AO interaction efficiency on the surface acoustic wave (SAW) frequency, waveguide parameters, and optical wavelength were obtained from the exact solution of SAW propagation in a layered structure. Results of experimental investigations on a GaAlAs-waveguide at the wavelengths of gallium arsenide ((lambda) ₀ equals 0.88 micrometers ) and gellium-neon ((lambda) ₀ equals 1.15 micrometers ) lasers in the frequency range of 100 - 500 MHz are presented.
