We report the nonlinear optical properties of polaritons in a single quantum well GaAs microcavity. Single and double resonance cavities have been used to enhance the nonlinear effect of a nonlinear medium in high-Q quality factor cavities due to the cavity field amplification. On the other hand, such a cavity can generate polaritons, which condense (Bose–Einstein condensation) for determined conditions, such as cavity detuning and polariton density. Here, we present experimental observations of the second harmonic generation from polaritons in a GaAs microcavity, which exhibit a 2 order higher efficiency than those from the usual method. Furthermore, the efficiency is particularly high when the polariton is a photon-like particle and in a condensed state.
