The phenomena arise from the bosonic character of the coupled exciton-photon modes of the system. The ability to manipulate and control the polariton dispersions in microcavities is shown to be a key factor underlying the new observations. The potential of such phenomena to form the basis of a new type of coherent light source ("polariton" lasers) and highly efficient optical parametric oscillators is discussed.Quantum MicrocavityNonlinear EmissionRelaxationDynamicsPhotoluminescenceBottleneckRegimetext::journal::journal article::research article
