Abstract

The coherent THz emission from cavity polaritons in a semiconductor microcavity, which consists of three 108 angstroms/102 angstroms GaAs/AlAs quantum wells, was examined. The sample exhibited a Rabi splitting of 5.7 meV at normal incidence at T = 4 K. The spectral sample design and large Rabi splitting made the observation of cavity polaritons from 4 K up to room temperature possible. A short laser pulse excited the sample with an incident photon density of <6·1010 photons/cm2, which is much smaller than the saturation density of the cavity polariton doublet. Three measurements were carried out simultaneously: coherent THz detection; time-resolved upconversion of the reflected beam; and spectral analysis of the reflection.
