Abstract
We consider the optical response of a realistic semiconductor quantum well, where the exciton polarizability is nonlocal and the confinement of the exciton wave functions is nonideal. Normal incidence reflectivity is calculated in the case of GaAs/Ga0.7 Al0.3 As single quantum well. No significant difference has been found in comparison with the numerical results obtained either by the local response calculation or by the ideal confinement approximation.
