Abstract:
The influence of a complex of elastic strains caused by technological stresses and external shear strains on the optical properties of cubic crystals has been analyzed. Data on the changes in optical symmetry of such crystals have been obtained. The changes in polarization characteristics of the radiation during propagation in both strained crystal and shear-strained nanoscale heterostructures have been studied. The effects of the acoustoelectronic and photoelastic deformation mechanisms on the changes in polarization properties of the radiation of nanoscale heterostructures have been compared.
