Owing to their feasibility for such a vast application range, frequency comb technology has seen major advances in terms of complexity, power requirements and size, leading to micro- to millimeter-sized frequency comb generators emitting continuous-wave-pumped Kerr combs and, more lately, soliton frequency combs based on third-order (χ⁽³⁾) nonlinearities [2].enfalseconference paper
