Optical frequency combs, consisting of mutually coherent and equally spaced spectral lines, provide a powerful means of synthesizing, distributing, and processing optical frequencies on chip. Among integrated photonic platforms, thin-film lithium niobate (TFLN) is particularly attractive for comb generation because it combines strong electro-optic (EO) functionality, accessible χ⁽²⁾ and χ⁽³⁾ nonlinearities, low-loss nanophotonic confinement, and versatile dispersion engineering. This review summarizes the physical foundations and representative realizations of TFLN combs, and discusses their applications in optical communication, microwave photonics, optical computing, and precision metrology. The integration of nonlinear functionality, EO control, and passive photonic components is expected to advance compact, energy-efficient comb sources and broaden the utility of TFLN in integrated photonics and quantum optics.
