Abstract

We present the detailed analysis of the spontaneous emission coupling factor of the micro cavity based on a 2D photonic crystal in an optically thin dielectric slab. We investigate the maximum (beta) value that can be achieved with this micro cavity 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 (beta) factor calculation that we developed. The method is based on the classical model for atomic transitions in a semiconductor active medium. Finite difference time domain method is used to solve the electromagnetic fields of the system and calculate the total radiated energy, as well as the energy radiated into the mode of interest.
