Extended polarized semiclassical model for quantum-dot cavity QED and its application to single-photon sources

Physical Review A, vol. 101

Abstract

We present a simple extension of the semiclassical model for a two-level system in a cavity, in order to incorporate multiple polarized transitions, such as those appearing in neutral and charged quantum dots (QDs), and two nondegenerate linearly polarized cavity modes. We verify the model by exact quantum master equation calculations and experimentally using a neutral QD in a polarization nondegenerate microcavity, and in both cases we observe excellent agreement. Finally, the usefulness of this approach is demonstrated by optimizing a single-photon source based on polarization postselection, where we find an increase in the brightness for optimal polarization conditions as predicted by the model.
