mode-locked laser （MLL）

optical frequency combs (OFCs)

photonic integrated circuits (PICs)

two main categories of comb sources in integrated photonics: semiconductor mode-locked lasers (SMLLs) and nonlinear frequency combs.

Kerr comb generation through microresonators (so called microcombs)

by simultaneously balancing dispersion against nonlinearity and loss against parametric gain, a microresonator in the anomalous group-velocity dispersion (GVD) regime can support fully mode-locked comb states called dissipative Kerr solitons (DKSs)

For most applications, the repetition rate of the comb needs to be low enough to interact with the electronics used for signal detection and processing, typically at RF frequencies of the order of tens of gigahertz or less.
