Distinguishing intrinsic photon correlations from external noise with frequency-resolved homodyne detection

Abstract In this work, we apply homodyne detection to investigate the frequency-resolved photon statistics of a cw light field emitted by a driven-dissipative semiconductor system in real time. We demonstrate that studying the frequency dependence of the photon number noise allows us to distinguish...
