Abstract
An analytic expression is obtained for the linear coefficients of photoelasticity in multilayer quantum-well structures having a sloping bottom in the region of the fundamental exciton resonance. The coefficients of photoelasticity are calculated for a GaAs/Al0.28Ga0.72As superlattice at the long-wavelength edge of the exciton ground-state resonance. It is shown that these coefficients for multilayer quantum-well structures with the sloping bottom which arises in a varizone quantum-well, are larger, and for those with a bottom slope determined by a constant electric field applied to the multilayer quantum-well structure, are lower than the same quantities for a superlattice with a rectangular quantum-well. The magnitude of the linear contribution of the piezoelectric field stimulated by the slope of the bottom of the quantum-well to the photoelasticity coefficient is calculated for piezoelectric superlattices and this is compared with the contribution introduced by the straining potential.
