Paper Abstract

In this experiment, we propose and demonstrate a novel exciton-exciton scattering process for the case of semiconductor microcavity exciton-polaritons. We show that the scattering rate should be enhanced due to the final state stimulation effect. We have observed the enhancement of the elastic exciton-exciton scattering rate in a semiconductor microcavity. The signature of this stimulated emission is in the enhancement of the scattering rate that is proportional to the final state occupation number. For this reason, we have interpreted the gain to be due to bosonic stimulation. This gain process for exciton- polaritons is distinctly different from that in a conventional photon laser, because of the fermionic nature of the exciton's constituents, the electron and hole.
