摘要

我们报告了世界纪录的高数据传输标准光纤从一个单一的光源。我们实现了44.2太比特每秒(Tb/s)的线路速率,仅使用c波段在1550nm,从而产生10.4比特/秒/赫兹的频谱效率。我们使用了一种新型的强大的微梳,称为孤子晶体,它具有强大的运行能力和稳定的产生能力,以及高固有效率,加上极低的48.9 GHz间距,可以实现64 QAM的高相干数据调制格式。我们在实验室实现了75公里标准光纤的无误差传输,并通过城域光纤网络进行了现场试验。这项工作证明了光学微梳在性能上超越其他方法的能力,适用于最苛刻的实际光通信应用。

Ultra-high bandwidth fiber-optic data transmission with a single chip source
We report world record high data transmission over standard optical fiber from a single optical source. We achieve a line rate of 44.2 Terabits per second (Tb/s) employing only the C-band at 1550nm, resulting in a spectral efficiency of 10.4 bits/s/Hz. We use a new and powerful class of micro-comb called soliton crystals that exhibit robust operation and stable generation as well as a high intrinsic efficiency that, together with an extremely low spacing of 48.9 GHz enables a very high coherent data modulation format of 64 QAM. We achieve error free transmission across 75 km of standard optical fiber in the lab and over a field trial with a metropolitan optical fiber network. This work demonstrates the ability of optical micro-combs to exceed other approaches in performance for the most demanding practical optical communications applications.
