For the first time a detailed study of hybrid mode-locking in two-section InAs/InP quantum dot Fabry-Pérot-type lasers is presented. The output pulses have a typical upchirp of approximately 8 ps/nm, leading to very elongated pulses. The mechanism leading to this typical pulse shape and the phase noise is investigated by detailed radio-frequency and optical spectral studies as well as time-domain studies. The pulse shaping mechanism in these lasers is found to be fundamentally different than the mechanism observed in conventional mode-locked laser diodes, based on quantum well gain or bulk material.
首次对两段式InAs/InP量子点法布里 - 珀罗型激光器中的混合锁模进行了详细研究。输出脉冲具有约8 ps/nm的典型向上啁啾，导致脉冲非常拉长。通过详细的射频和光谱研究以及时域研究，对导致这种典型脉冲形状和相位噪声的机制进行了研究。发现这些激光器中的脉冲整形机制与基于量子阱增益或体材料的传统锁模激光二极管中观察到的机制根本不同。
