Abstract
We report on the first observation of coherent terahertz (THz) radiation emitted from an unbiased semiconductor microcaivty at T=4.7K. The MC consists of three 108Å/102Å GaAs/AlAs placed at the center of a λ cavity. The THz radiation is emitted after a resonant excitation of the two cavity polaritons with a short pulse. We attribute the THz radiation to dipole oscillations at the vacuum Rabi splitting frequency between the photon and the exciton states.
