Acousto-optical diagnostics of Gulyaev-Bleustein waves under Fresnel reflection conditions

Diffraction of light by ultrasonic Gulyaev-Bleustein waves is studied under Fresnel reflection conditions. It is shown that Gulyaev-Bleustein waves propagating in GaAs-AlGaAs structures can be detected by acousto-optic methods under conditions for Fresnel reflection of diffracted waves. It has been established that the considered structures are promising for design of multichannel acousto-optical deflectors and modulators. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 75, No. 4, pp. 583–587, July–August, 2008.
