Experimental setup. DSF: dispersion shift fiber; EDFA: erbium-doped fiber amplifier; F1–F3: filters; FC1: 90/10 fiber coupler; FC2: 50/50 fiber coupler; FPC1 and FPC3: fiber polarization controllers; HBT: Hanbury Brown–Twiss interferometer; PBS1 and PBS2: polarization beam splitters; VOA1 and VOA2: variable optical attenuators; SPD1 and SPD2: single photon detectors.
