The emission properties of single quantum dots in planar microcavities are studied experimentally and theoretically. Fivefold enhanced spontaneous emission outside the microcavity is found for dots in resonance with the cavity mode, relative to detuned dots. Using high-power excitation we obtain the in-plane cavity dispersion. Near-field images of the emission show spatial distributions of several micrometers for resonant dots, which decrease in size with the detuning from resonance. These experimental findings are explained using a simple and intuitive model.
