Abstract
We theoretically investigate the optical response of a quantum dot, embedded in a microcavity and incoherently excited by pulsed pumping. The exciton and biexciton transitions are off-resonantly coupled with the left- and right-polarized mode of the cavity, while the two-photon resonance condition is fulfilled. Rich behaviors are shown to occur in the time dependence of the second-order correlation functions which refer to counter-polarized photons. The system's dynamics turns out to be much faster than typical experimental detection times. The experimentally accessible time-averaged quantities confirm that such a dot-cavity system behaves as a good emitter of single polarization-correlated photon pairs.
