There has been a great dealt of interest in recent years in developing nanophotonic systems for use as single-photon and entangled photon sources. One promising class of such systems is semiconductor photonic crystal slabs that contain line and/or point defects. In this talk I will discuss the formalism that we have developed to model nonlinear photon generation and propagation in coupled-defect cavities in photonic crystal slabs. The key to our approach is the non-hermitian projection of the photon dynamics onto a set of lossy and potentially non-orthogonal cavity quasi-modes. I will apply our approach to single quantum dots coupled to multiple cavities and to photon pair generation due to spontaneous four-wave mixing in coupled optical resonator waveguides.
