This chapter describes the photoluminescence properties of a solid-state cavity quantum electrodynamics (CQED) system, consisting of a single quantum dot (QD) coupled to a photonic crystal (PC) defect cavity. It addresses in particular the phenomenon of cavity feeding, that is, the efficient luminescence at the cavity frequency even for large detunings. The chapter presents a theoretical model of cavity feeding that takes into account the coupling to wetting-layer states. We find excellent agreement between simulations based on this model and experimental observations in the case of large detuning. In addition, the influence of acoustic phonons for the small-detuning case is discussed.
