307Citations 7Altmetric Metrics Abstract Optical frequency combs offer an unrivalled degree of frequency measurement precision that underpins the advance of modern technology in both fundamental science and commercial contexts. Recent progress in integrated photonics provides an attractive route to realize opt...
Microresonator frequency combs harness the nonlinear Kerr effect in an integrated optical cavity to generate a multitude of phase-locked frequency lines. The line spacing can reach values in the order of 100 GHz, making it an attractive multi-waveleng
