Abstract

We present a theoretical study of a quantum-dot-based microcavity laser where two nearly degenerate high-Q modes are involved in the laser dynamics. To analyze the coupled carrier-photon system we have extended a single mode microscopic semiconductor theory to the case of two modes and have also taken the crosscorrelation functions into account.

Our theoretical results show that the mode which loses the mode competition exhibit super-thermal photon bunching (inline image). This interesting feature is traced back to mode coupling induced by the gain medium.The strong correlation between the two modes is revealed by calculation of the photon cross correlation functions.
