摘要
A theoretical study of the first-order coherence of quantum-dot-based microcavity lasers is presented for the case of continuous-wave excitation. The theory is based on the equation of motion technique and cluster-expansion scheme which allows to incorporate semiconductor specific effects in a straightforward manner. The correlation function g((1))(tau) and the corresponding coherence time is computed including photon-carrier and photon-photon correlations with respect to the delay time tau up to the quadruplet level of the cluster-expansion scheme.
