Abstract
Although the theory of photonic crystal cavities has been widely investigated, the interpretation of the experimental emission spectra still creates a challenge because the spontaneous emission enhancement is a spatially and spectrally varying property. We present a comprehensive simulation and analysis of the emission spectrum of photonic crystal cavities, considering the spatially and spectrally varying spontaneous emission enhancement, the material loss, and the coupling efficiency to the detection system. The simulations have been performed with a 3D finite-element Maxwell solver and an efficient mode expansion scheme. They have been compared to measured spectra and show very good agreement.
