The spin dynamics of cavity polaritons, in the non-linear regime, present a novel and striking behaviour of the degree of polarization of photoluminescence. It reaches its maximum value at a finite time after excitation with a light pulse, and is strongly influenced by the exciton-cavity detuning. I

We present a full analysis of exciton dynamics in a GaAs λ/2 bulk microcavity following excitation by ultrafast laser pulses. Coherent dynamics was probed by means of an interferometric technique; beating and dephasing times were studied for various excitation intensities. At high incident power, po
The behaviour of cavity polaritons is strongly affected by disorder scattering in traditional inorganic semiconductor microcavities and, much more, in organic semiconductor microcavities. In the presence of disorder coherent cavity polaritons having a well defined in-plane wavevector coexist with in
