Recovering the Hidden Photon Bunching from Two-Photon Absorption Based on Polarization Modulation
Sheng Luo, Wanting Xu, Yu Ling Zhou +2 more
The polarization modulation is employed to recover the hidden photon bunching effect of broadband chaotic light at ultrashort timescale based on two-photon absorption detector. Not only the hidden second-order coherence function in the two-photon absorption counting can be obtained, but also the disappeared two-photon interference pattern based on two-photon absorption detection can be recovered. In theory, polarization matrix and two-photon interference probability amplitudes matrix are combined to develop polarized two-photon interference terms, which is in good agreement with the experimental results. The proposed method may help to develop future optical interferometry, optical polarimetry.
