摘　　要：A source of quantum correlated photon pairs in the 155Onto telecom band obtained by a pumping 11 m photonic crystal fiber with lOps 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.A source of quantum correlated photon pairs in the 155Onto telecom band obtained by a pumping 11 m photonic crystal fiber with lOps pulse trains is experimentally demonstrated.
