Summary form only given. The strong coupling between quantum well exciton and cavity photon leads to the so-called microcavity polaritons whose energy dispersion is very sharp due to the photon component. Unlike bare excitons, the optical response of polaritons is very sensitive to the incidence angle of the exciting laser beams. This means that the dispersive character can drastically affect nonlinear wave-mixing processes. We present new results about nonlinear wave-mixing due to polariton-polariton correlations. In particular, we consider an angle-resolved pump-probe experiment where the probe is assumed at normal incidence, while the pump has a finite incidence angle. The polariton-polariton correlations are taken into account through a microscopic Hamiltonian treatment including exciton-exciton interaction.
