Photon statistics and time evolution of photon correlations in semiconductor microcavity lasers — •Jan Wiersig1, Christopher Gies2, and Frank Jahnke2 — 1Institut für Theoretische Physik, Universität Magdeburg, 39016 Magdeburg — 2Institut für Theoretische Physik, Universität Bremen, 28334 Bremen
Nanophotonic devices made of semiconductor quantum dots coupled to microcavities have a variety of potential applications including ultra-low threshold lasers and single-photon sources. In this talk we discuss a microscopic theory for the photon correlation functions g(1)(τ) and g(2)(τ) describing the first and second-order coherence of semiconductor quantum-dot-based microcavity lasers [1,2]. Our theory predicts interesting and unexpected decay properties of the correlation functions. We explain these findings and compare them to recent experiments [3-5].
