Abstract

We derive an explicit operational method for calculating the spatial correlations that maximize the radiation efficiency of three-dimensional, primary, Schell-model sources. We show that the optimal correlation function depends on the source intensity. For sufficiently large and uniform sources, we find that the optimal isotropic spatial correlations are given by a universal result that is closely related to blackbody radiators. Isotropic model sources are considered as examples.
