INFLUENCE OF STRUCTURAL DISORDER AND LIGHT COUPLING ON THE EXCITONIC RESPONSE OF SEMICONDUCTOR MICROCAVITIES

The interplay between structural disorder, Coulomb interaction, and li ght-coupling effects is investigated for high-quality quantum wells in a semiconductor microcavity. The independently measured experimental susceptibility of a single quantum well in linear dispersion theory yi elds excellent agreement with a series of measured reflectivity spectr a for a variety of microcavity and distributed Bragg structures, showi ng that the disorder-averaged response of the exciton in its quantum w ell determines the optical response.
