Abstract
We employ a pump-induced polarization rotation scheme for the quantitative study of four-particle (exciton-exciton) correlations in a strongly coupled semiconductor microcavity. From the measured rotation angle in the chi((3) )-regime, in which the nonlinear response is linearly proportional to pump intensity (I-pump), we evaluate the absolute value of anharmonicity of two- dimensional excitons. Deviation from the chi((3))-regime is observed beyond I-pump = 0.2 kW/cm(2).
