摘要
Semiconductor mode-locked lasers(MLLs)can provide coherent optical frequency combs(OFCs)with high repetition rates and output power,which have been recognized as potential multi-wavelength sources used in optical communication field due to their compactness,high-efficiency,and low-cost properties.In this article,we have reviewed recent development of semiconductor MLL-based frequency comb generation.Different approaches of semiconductor MLLs for OFC generation are synoptically summarized based on various material platforms.The representative progress of III-V semiconductor MLLs on III-V platform and especially on Si substrates is both discussed for the applications in integrated silicon photonics.
