Abstract
Low-temperature time-resolved luminescence experiments with 3-ps resol ution have been performed on quantum-well excitons embedded in a nongu iding half-wave microcavity that displays the exciton-photon mode spli tting. The spontaneous-emission dynamics of each of the two split comp onents was studied as a function of the exciton-cavity detuning under resonant optical excitation. The spontaneous-emission decay rate is si gnificantly modified with respect to the cavityless situation and its detuning dependence is accounted for by the strong radiative coupling between the radiant exciton states and the cavity photon modes.
