Single mode performance of a single mode injected locked quantum dot laser

An injection locked QD laser is demonstrated to provide single longitudinal mode operation with a 40dB SMSR and an improvement in RIN peak from 1.3-2.3GHz. Alpha factor is measured to be 0.8. © 2005 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.
