Abstract

An analytical solution to the boundary value problem for the existence of a Bleustein-Gulyaev piezoelectric surface wave in GaAs and other piezoelectric cubic crystals is developed. Numerical solutions for Bleustein-Gulyaev waves in a number of crystals of 43 m and 23 symmetry classes are presented. These include commonly used materials such as GaAs, GaP, InSb, InAs, Bi₁₂GeO₂₀, and Bi₄Ge₃O₁₂. The results are then used to investigate light diffraction by Bleustein-Gulyaev waves in GaAs. Cases of both plane-wave acoustooptic and guided optical-wave interaction are considered. A numerical solution for a guided-wave acoustooptic collinear interaction in a GaAs-GaAlAs waveguide is presented and discussed
