Quantum-well excitons in a semiconductor microcavity are studied by photoluminescence and input-output experiments. Emission peaks at both longer and shorter wavelengths are observed, indicating the importance of exciton-acoustic-phonon interaction at low temperature. Pump-probe experiments show that the probe beam can be either amplified or attenuated, depending on the energies of the pump and the probe. The dynamics of this process are described by a simple rate-equation model.
