本文报道了用量子阱混合技术制作的单片集成无源波导实现的C波段两段式AlGaInAs/InP锁模激光器的飞秒脉冲输出。在没有任何外部脉冲压缩的情况下，以~38 GHz的重复频率产生具有490 fs脉冲持续时间的洛伦兹脉冲，据我们所知，这是来自任何直接电泵浦量子阱半导体锁模激光器的最短脉冲。锁模范围相对较大，超窄脉冲宽度在很宽的驱动条件范围内非常稳定。
We report femtosecond pulses from a passive C-band two-section AlGaInAs/InP mode-locked laser with a monolithically integrated passive waveguide made by quantum well intermixing. Without any external pulse compression, Lorentzian pulses are generated at a repetition frequency of ~38 GHz with 490 fs pulse duration, which is, to the best of our knowledge, the shortest pulse from any directly electrically pumped quantum well semiconductor mode-locked laser. The mode-locking range is relatively large and the ultranarrow pulse width is very stable over a broad range of driving conditions.
