Effect of Optical Feedback on 17-GHz Quantum Dash Based Mode Locked Lasers
01 January 2010
: Optical feedback tolerance is investigated for a quantum-dash-based passive modelocked laser. We observe a drastic reduction of the radio frequency spectrum linewidth, even beyond the coherence collapse regime. ©2010 Optical Society of America OCIS codes: (140.4050) Mode-locked lasers, (250.5590) Quantum-well, -wire and -dot devices
