Abstract We model the parametric photoluminescence process of laterally confined polaritons in a mesa structure, patterned on a semiconductor microcavity. Parametric processes are described within the lowest order in the polariton–polariton interaction. We show how a plane‐wave pump produces simultaneously several signal–idler pairs, due to the broken translational symmetry, the finite polariton linewidths, and the presence of a continuum of polariton states above the shallow mesa barrier. We discuss under which conditions of pump and detuning, the simple three‐mode picture for the parametric process is recovered. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
