论文摘要
通过对与ITU-T G.652D的电信标准相对应的纤维传播的宽带光子对之间的非局部分散补偿是通过对它们之间时间相关性的细粒度测量进行了研究的。我们通过调整光子对的传播距离来保留接近我们检测设备的有效仪器分辨率（41.0 $ \ pm $ 0.1PS），通过调整光子对的传播距离（41.0 $ \ $ 0.1ps）来证明非局部色散补偿的近乎理想水平。实验数据表明，可以通过相对较大的纤维增量（1km）来实现此程度的补偿，与现实世界部署兼容。最终，在两个多段的10公里部署的大都市纤维上，光子正时相关性被保留至51PS $ \ pm $ 21ps。
Nonlocal dispersion compensation between broadband photon pairs propagated over fiber corresponding to the ITU-T G.652D telecommunications standard was studied via fine-grained measurements of the temporal correlation between them. We demonstrated near-ideal levels of nonlocal dispersion compensation by adjusting the propagation distance of the photon pairs to preserve photon timing correlations close to the effective instrument resolution of our detection apparatus (41.0$\pm$0.1ps). Experimental data indicates that this degree of compensation can be achieved with relatively large fiber increments (1km), compatible with real-world deployment. Ultimately, photon timing correlations were preserved down to 51ps$\pm$21ps over two multi-segmented 10km spans of deployed metropolitan fiber.
