FM mode-locking in monolithic semiconductor lasers

FM mode-locking in monolithic semiconductor lasers is investigated for the first time, using a travelling-wave laser model. The effects of phase modulation depth and non-zero alpha factor on pulse quality and pulse-width are discussed. © 2004 Optical Society of America.

20GHz colliding pulse mode-locking of ingaas quantum dot lasers

Colliding pulse mode-locking is demonstrated for the first time in quantum-dot lasers. Close to transform limited, 7ps, 20GHz pulses are achieved using an absorber length considerably longer than typically used in similar quantum-well lasers. © 2004 Optical Society of America.
