Abstract

Novel oscillator strength transfer phenomena induced by the exciton-exciton correlation were studied. Starting from a Hamiltonian of interacting excitons, the δ- quantum-well susceptibility to the weak probe beam in presence of a population of δ+ excitons was analytically calculated. The optical spectra of the microcavity were calculated in the framework of the linear dispersion theory by inserting the susceptibility formula in a transfer matrix calculation.
