Abstract
The remarkable acousto-optical properties of superlattices for light wavelength near the condition of the Bragg reflection at the interfaces are reported here for the first time. Because of the assistance of a reciprocal lattice vector in the phase-matching condition, the collinear coupling between the light and ultrasonic waves becomes possible in the superlattice. At the same time, the diffraction efficiency is strongly increased by an optical resonance effect in the superlattice. Acousto-optical devices based on semiconductor superlattice structures are proposed, which can be very efficient, rapid, and compact.Keywords
