Photon statistics

Liangyun Liu, Yuzhu Wang

In this paper, we calculate the photon statistics of resonance fluorescence of a two-level atom driven by a laser field. The results show that the photon statistics tend to Poissonian if we consider the photon statistics starting from the ground state of the atom. We propose a possible method to test the photon statistics of resonance fluorescence.

An original approach has been developed to extract information on the photon distribution function recorded by the photocount method in the presence of interference. Photon statistics reconstruction has been studied in the presence of two types of interference: dark counts and background radiation. The calculation has been performed using a characteristic function. Correctly reconstructing photon statistics and appropriate experimental conditions have been discussed. The obtained results can be used in measuring photon statistics of low-photon radiation sources and non-classical light fields.

An efficient scheme for photon statistics measurement is presented based on the Hanbury-Brown-Twiss configuration. We set the sampling time Ts to satisfy the relationship of TslTdlTm, where Td is the dead time of each detector and Tm is the laser pulse repetition period. And each single photon detector cannot detect more than one photon in each pulse. The approach can sufficiently eliminate the influences of the detector's dead time on photon statistics. At last, the photon statistics of coherent field is experimentally determined.
