Abstract

Strongly angular-dependent emission properties are observed from a semiconductor microcavity pumped along a critical angle of incidence. In contrast to the luminescence from conventional semiconductor heterostructures, the emission is completely asymmetrical with respect to the sample normal. The results imply that parametric scattering dominates the energy relaxation of polaritons, and is enhanced by the deformed shape of the dispersion relations.
