摘要：

A source of quantum correlated photon pairs in the 1550 nm telecom band obtained by a pumping 11 m photonic crystal fiber with 10 ps pulse trains is experimentally demonstrated. We investigate how the birefringence of the fiber influences the purity of the photon pairs. We also present the frequency correlation of the signal and idler photon pairs. The experimental results are useful for developing a compact source of photon pairs well suited for quantum communication.
