A portable polarization-entangled quantum photon source with an optical output as well as an auxiliary electronic output in the 1550 nm telecom band is developed based on spontaneous four-wave mixing in a dispersion-shifted fiber. The polarization-entangled photon pairs of signal and idler waves with wavelengths of 1558.17 nm and 1548.51 nm are outputted from the standard single-mode fiber port, respectively. The electrical signals with tunable delay and frequency division are outputted from the coaxial cable port, which are used for the single photon detectors and the data acquisition system. The results show that when the photon generation rate in a single channel is about 0.0007 pair/pulse, the ratio between the coincidence count rate and the accidental coincidence count rate is up to 22.8, and the visibility of polarization-entangled interference fringes is 87%.
