Abstract

In semiconductor microcavities, the Strong Coupling Regime gives rise to mixed exciton-photon states named microcavity polaritons. For very low carrier densities, polaritons (like excitons) are expected to obey Bose stastitics and may give rise to stimulated mechanisms. However, for large carrier densities, the fermionic nature of the exciton constituents dominates and leads to broadening of the polariton mode and reduction of the exciton oscillator strength [1].
