Propagation effects in semiconductor multiple quantum well structures
T. Stroucken, Andreas Knorr, S. W. Koch +2 more
The dynamics of radiatively coupled quantum well excitons is investigated. It is shown that collective effects determine the optical response of semiconductor multiple quantum well stacks. In multiple quantum well Bragg structures, collective phenomena manifest themselves as a superradiant decay of coherent electronic excitations. In anti-Bragg structures, the optical coupling induces an interwell energy transport and a splitting of the excitonic resonance.
