Abstract

Dual-frequency combs have enabled significant advances in applications such as temporal sensing and spectroscopy [1]. The recent development of the Kerr cavity soliton frequency comb has opened a new approach for generating dual-frequency combs with advantageous characteristics [2, 3]. That approach relies on the generation of two individual Kerr cavity soliton frequency combs with different repetition rates either using two different resonators or different modes within a single resonator [5, 6] to obtain comb bandwidths on par with many microresonator platforms.
