Full photon statistics for superradiant quantum-dot-microcavity lasers via the Monte Carlo wave-function method — •Sergej Neumeier and Jan Wiersig — Institut für Physik, Otto-von-Guericke-Universität Magdeburg, Postfach 4120, D-39016 Magdeburg, Germany

Superradiance, the enhancement of spontaneous emission, appears due to radiative coupling between emitters. Using this effect highly efficient quantum-dot nanolasers can be build [1]. It has been experimentally observed that this coupling also leads to an enhanced photon bunching [2]. These inter-emitter coupling effects have been described by simulating open systems in quantum optics [3,4] using the Monte Carlo wave-function method [5,6,7]. The method gives access to the full photon statistics. Experimentally the full photon statistics, e.g. auto-correlation functions (g⁽²⁾(0) etc.) and the photon-number distribution p_n, can be measured using a transition edge sensor [8].

We use the Monte Carlo wave-function method to study a continuously driven (cw) quantum-dot ensemble interacting with a single-mode light field in a microcavity.
