基于微谐振器的频率梳是波分复用（WDM）光源的有力竞争者。最近的实验表明，微谐振器梳有潜力用单个激光泵浦装置取代大量的波分复用激光器。然而，以前的演示集中在短距离的小跨度链路上，以牺牲传输距离为代价获得了令人印象深刻的吞吐量。在这里，我们报告了使用基于微谐振器的梳状源的第一次远程相干通信演示。我们将偏振复用（PM）正交相移键控数据调制到梳状线上，允许在单模光纤中传输超过6300公里。在第二个实验中，我们使用PM 16正交调幅格式达到了700公里以上。据我们所知，这些结果代表了使用集成梳状源实现的最长光纤传输。(C) 2017年美国光学学会
Microresonator-based frequency combs are strong contenders as light sources for wavelength-division multiplexing (WDM). Recent experiments have shown the potential of microresonator combs for replacing a multitude of WDM lasers with a single laser-pumped device. Previous demonstrations have however focused on short-distance few-span links reaching an impressive throughput at the expense of transmission distance. Here we report the first long-haul coherent communication demonstration using a microresonator-based comb source. We modulated polarization multiplexed (PM) quadrature phase-shift keying-data onto the comb lines allowing transmission over more than 6300 km in a single-mode fiber. In a second experiment, we reached beyond 700 km with the PM 16 quadrature amplitude modulation format. To the best of our knowledge, these results represent the longest fiber transmission ever achieved using an integrated comb source. (C) 2017 Optical Society of America
