WebFor Kerr frequency combs the typical range is from around 10 GHz to 1 THz. The coherent generation of an optical frequency comb from a continuous wave pump laser is not a unique property of Kerr frequency combs. Optical frequency combs generated with cascaded optical modulators also possess this property. Webbeen achieved by using microresonators with high quality factors [17,18,24–26]. Another important figure of merit is the power conversion efficiency, i.e. how much power is converted from the single-frequency pump to the gen-erated new frequency lines. Most phase coherent micro-combs have poor conversion efficiency, which is generally
