论文摘要
Micro-Combs [1-4]，由集成的微型腔谐振器生成的光频梳，提供其批量同行的全部潜力[5,6]，但在集成的足迹中。在许多领域（包括光谱[12,13]，Microwave Photonics [14]，频率合成[15]，光学范围[16,17]，量子范围[16,17]，量子源[18,19,9,9,9,9,9,9,9,9,9,9,9,9,9,9,19，，发现了颞孔状态（DKS耗散性的Kerr孤子）[4,7-11] [4,7-11]作为建模微生物建模的一种手段[4,7-11]的一种方法，[12,13]，频率合成[15]和量子。他们最有前途的应用之一是光纤通信，它们使得超平行的超高容量多重数据传输[22,23]。在这里，通过使用称为孤子晶体的新型微型汤[11]，我们使用单个集成芯片源在标准光纤上实现了前所未有的数据传输。我们在1550nm处使用电信c频段（频谱效率），每秒的线路速率为每秒44.2 terabits，这是一个至关重要的性能度量，为10.4位/s/s/hz。孤子晶体表现出强大而稳定的产生和操作以及高内在效率，加上48.9 GHz的孤子微重栓间距较低，可以使用64 QAM的非常高相干数据调制格式（正交振幅调节）。我们证明了实验室中75公里的标准光纤以及安装的大都市光纤网络的现场试验中的无误差传输。孤子晶体在不稳定或反馈控制的情况下运行的能力极大地帮助了这些实验。这项工作证明了光学孤子晶体微型小子在苛刻和实用的光学通信网络中执行的能力。
Micro-combs [1 - 4], optical frequency combs generated by integrated micro-cavity resonators, offer the full potential of their bulk counterparts [5,6], but in an integrated footprint. The discovery of temporal soliton states (DKS dissipative Kerr solitons) [4,7-11] as a means of modelocking microcombs has enabled breakthroughs in many fields including spectroscopy [12,13], microwave photonics [14], frequency synthesis [15], optical ranging [16,17], quantum sources [18,19], metrology [20,21] and more. One of their most promising applications has been optical fibre communications where they have enabled massively parallel ultrahigh capacity multiplexed data transmission [22,23]. Here, by using a new and powerful class of microcomb called soliton crystals [11], we achieve unprecedented data transmission over standard optical fibre using a single integrated chip source. We demonstrate a line rate of 44.2 Terabits per second using the telecommunications C band at 1550nm with a spectral efficiency, a critically important performance metric, of 10.4 bits/s/Hz. Soliton crystals exhibit robust and stable generation and operation as well as a high intrinsic efficiency that, together with a low soliton microcomb spacing of 48.9 GHz enable the use of a very high coherent data modulation format of 64 QAM (quadrature amplitude modulated). We demonstrate error free transmission over 75 km of standard optical fibre in the laboratory as well as in a field trial over an installed metropolitan optical fibre network. These experiments were greatly aided by the ability of the soliton crystals to operate without stabilization or feedback control. This work demonstrates the capability of optical soliton crystal microcombs to perform in demanding and practical optical communications networks.
