Abstract

The third-order nonlinear response of the strongly coupled cavity-exciton system shows strong signatures of the long- and short-living four-particle correlations, which manifest themselves in polarization-sensitive four-wave mixing (FWM).¹ In particular, the long-living correlation due to the biexciton may dominate in the third-order nonlinearity of the exciton-cavity system.²
