Abstract
The comparative consideration of efficiencies for all possible mechanisms of acousto-optic interaction in resonant photoelastic structures on base of AlGaInAs is carried out. It is found that the most effective mechanism is the resonant one due to a potential deformation interaction of two-dimensional excitons in multiquantum wells (MQW). Calculation of characteristic photoelastic constants for a general situation with different broadened absorption lines of an exciton resonance is carried out. Some peculiarities of photoelastic resonance under influence of both homogeneous and inhomogeneous line broadening are firstly established and explained.
