光频梳最初是为计量学而开发的，现在在更广泛的研究主题中变得越来越普遍，包括光通信、光谱学以及无线电或微波信号处理。然而，这些领域的应用需求可能更具挑战性，因为它们需要对温度变化具有高耐受性的紧凑型光源，这些光源能够提供平坦的梳状光谱、每音调高功率、窄线宽和高光学信噪比。这项工作报告了一个平面的，高功率的频率梳在电信频段使用17毫米的完全集成的硅芯光纤作为参数混频器的产生。我们的全光纤无腔光源将平面波导结构的材料优势与光纤平台的有利特性相结合，实现了30 nm带宽的梳状光源，包含143个音调，线宽<3 kHz，平坦度12 dB，整个光谱区域的OSNR>30 dB。硅芯光纤是一种高度非线性的波导，它结合了光纤和平面波导系统的优点。在这里，作者演示了使用全光纤集成硅芯光纤作为非线性混频器的频率梳产生。
Originally developed for metrology, optical frequency combs are becoming increasingly pervasive in a wider range of research topics including optical communications, spectroscopy, and radio or microwave signal processing. However, application demands in these fields can be more challenging as they require compact sources with a high tolerance to temperature variations that are capable of delivering flat comb spectra, high power per tone, narrow linewidth and high optical signal-to-noise ratio. This work reports the generation of a flat, high power frequency comb in the telecom band using a 17 mm fully-integrated silicon core fibre as a parametric mixer. Our all-fibre, cavity-free source combines the material benefits of planar waveguide structures with the advantageous properties of fibre platforms to achieve a 30 nm bandwidth comb source containing 143 tones with <3 kHz linewidth, 12 dB flatness, and >30 dB OSNR over the entire spectral region. Silicon core fibre is a highly nonlinear waveguide that combines the benefits of both fibre and planar waveguide systems. Here, the authors demonstrate frequency comb generation using a fully-fibre integrated silicon core fibre as a nonlinear mixer.
