实验证明了用10ps脉冲串泵浦11m光子晶体光纤获得1550 nm电信波段量子关联光子对的源。我们研究了光纤的双折射如何影响光子对的纯度。我们还给出了信号光子对和闲置光子对的频率关联。这些实验结果对于开发适合于量子通信的紧凑型光子对源是有用的。
A source of quantum correlated photon pairs in the 1550nm telecom band obtained by a pumping 11m 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.
