Semiconductor theory for higher order photon auto-correlation functions of quantum dot microcavity lasers — •Heinrich A. M. Leymann, Alexander Foerster, and Jan Wiersig — Otto-von-Guericke-Universität Magdeburg
Semiconductor quantum dots (QDs) are of considerable interest due to their potential for device applications such as lasers [1] and non-classical light sources, as well as fundamental studies. We present a theory for the higher order photon auto-correlation functions g(3)(0), g(4)(0) based on an equation of motion technique. Starting from the semiconductor model described in [2] we present a general method to expand this theory to higher orders. The coherence properties of light emitted by QD based microcavity lasers are discussed. Also the convergence of the cluster expansion technique is investigated. Furthermore, photon anti-bunching for high fidelity cavity lasers near the threshold is discussed.
