Abstract
We characterize an entangled-photon-pair source that produces signal and idler photons at 1533 nm and 1567 nm using fiber-assisted signal-photon spectroscopy. By erasing the polarization distinguishability, we observe interference between the two down-conversion paths. The observed interference signature is closely related to the spectral correlations between photons in a Hong-Ou-Mandel interferometer. These measurements suggest good indistinguishability between the two down-conversion paths, which is required for high entanglement visibility.
摘要
我们利用光纤辅助信号光子光谱法对一个纠缠光子对源进行了表征，该源产生波长为1533纳米和1567纳米的信号光子和闲置光子。通过消除偏振可区分性，我们观察到了两条下转换路径之间的干涉。观察到的干涉特征与Hong-Ou-Mandel干涉仪中光子之间的光谱相关性密切相关。这些测量结果表明两条下转换路径之间具有良好的不可区分性，这是实现高纠缠可见度所必需的。
