Photon seeding has been shown to reduce timing jitter in modelocked semiconductor
lasers1, 2 and in gain-switched semiconductor lasers. 3 Reduction of timing jitter is crucial …

We report a method that enables an external‐cavity semiconductor laser to be actively mode

We experimentally compare the linewidth of the individual modes of an extended cavity
semiconductor laser when it operates mode locked and when it operates single mode. We …

We report the generation of optical pulse trains with 380 as of residual timing jitter (1 Hz-1

The pulse train from a synchronously pumped modelocked 850 nm CSP semiconductor
laser in a grating cavity is found to be fluctuating in amplitude and phase (relative to the …

We demonstrate the suppression of intensity fluctuations, which are known as mode partition
noise, in a multiwavelength semiconductor laser by using a hybrid mode-locking scheme …
