Tuning Kerr-Soliton Frequency Combs to Atomic Resonances

Apr 05, 2019  Dissipative-Kerr-soliton (DKS) frequency combs in nonlinear microresonators, which offer small footprints and low power consumption, can be used for optical metrology and communication. Ultrabroadband DKS combs at near-infrared frequencies remain largely unexplored, though, for lack of suitable group-velocity dispersion, reliable fabrication, and a robust method for soliton generation.
