Abstract

We report the generation of an optical frequency comb featuring a 28 THz bandwidth, sustained by a single 80 fs cavity soliton recirculating in a fiber Fabry–Pérot resonator. This large spectrum is comparable to frequency combs obtained with microresonators operating in the anomalous dispersion regime. Thanks to the compact design and the easy coupling of the resonator, cavity solitons can be generated in an all-fiber experimental setup with a continuous wave pumping scheme. We also observe the generation of a dispersive wave at higher frequencies, which is supported by higher-order dispersion. These observations align remarkably well with both numerical simulations and the established theory of cavity solitons.
