Near-field intensity correlations in parametric photo-luminescence

We study the spatiotemporal pattern of the near-field intensity correlations generated by parametric scattering processes in a planar optical cavity. A generalized Bogolubov–de Gennes model is used to compute the second-order field correlation function. Analytic approximations are developed to understand the numerical results in the different regimes. The correlation pattern is found to be robust against a realistic disorder for state-of-the-art semiconductor systems.
