Soliton Microcombs with Novel Dispersion

We theoretically and numerically investigate the formation of soliton frequency combs in driven, passive resonators with novel dispersion profiles. Specifically, we explore multi-peak and purely high-order even dispersion. These novel solitons could be observed experimentally in integrated Kerr microresonators and passive fiber cavities, offering strong potential for applications in frequency comb spectroscopy, self-referencing, and telecommunications.
