Nonlinear Effects in Dense Two-Dimensional Exciton-Polariton System

Abstract

Angle resolved emission spectra of MCs with quantum wells embedded in the active layer have been investigated under conditions of resonant excitation into the lower polariton (LP) branch. The conditions have been found at which macroscopic filling at the LP branch bottom is reached in the strong coupling regime. Under these conditions strong nonlinear effects in the intensity and the degree of polarization of polariton emission have been observed and investigated. The experimental dispersion of renormalized cavity mode and its strong narrowing have been explained using an interacting polariton model predicting that the coupling between the LP mode E(LP)(k) and the mode E*(k)= 2hw - E(LP)(k +2k(excitation) is qualitatively different from that of exciton and photon.
