We present the detailed analysis of the spontaneous emission coupling factor ( factor) of the microcavity based on a 2D photonic crystal in an optically thin dielectric slab. We i n vestigate the maximum value that can be achieved with this microcavity and discuss its dependence on the quantum well position, as well as on the pumping area diameter. The analysis is performed using the general method for the factor calculation that we developed. The method is based on the classical model for
