Temporal CW polarization-tomography of photon pairs from the biexciton radiative cascade: theory and experiment
Abstract
We study, experimentally and theoretically, temporal correlations between the polarization of photon pairs emitted during the biexciton-exciton radiative cascade from a single semiconductor quantum dot, optically excited by a continuous-wave light source. The system is modeled by a Lindbladian coupled to two Markovian baths: One bath represents the continuous light source, and a second represents the emitted radiation. Very good agreement is obtained between the theoretical model that we constructed and a set of 36 different time resolved, polarization correlation measurements between cascading photon pairs.
