Abstract

Optical frequency combs are very attractive for many applications, in particular, signal processing, communication applications [1], time and frequency metrology. Mode locked semiconductor lasers (MLL) are ideal candidates for the generation of phase locked optical frequencies owing to their compactness, high repetition rates, low noise and high power performances. However, passively MLLs are subjected to timing instabilities in long term operation due to various noise sources (intracavity and environmental noises).
