In this paper, we introduce a hybrid three-dimensional photoniccrystal cavity with an embedded quantum dot, and investigate the dynamics of the cavity-quantum dot system. The general procedure of modelling such a practical structure is presented, where the master equation is solved on the basis of the parameters obtained from defect mode analyses. According to our study, this structure can be engineered to achieve a nearly deterministic single photon gun. The excitation power is found to have an optimal value in terms of photon emission efficiency. Large excitation pulse duration is believed to cause a spurious peak in the second-order coherence measurement.
