We demonstrate passive harmonic mode locking of a quantum-well laser diode designed to support a discrete comb of Fabry-Perot modes. Spectral filtering of the mode spectrum was achieved using a nonperiodic patterning of the cavity effective index. By selecting six modes spaced at twice the fundamental mode spacing, near-transform-limited pulsed output with 2 ps pulse duration was obtained at a repetition rate of 100 GHz.
我们演示了一种量子阱激光二极管的被动谐波锁模，该激光二极管设计用于支持 Fabry-Perot 模式的离散梳状结构。通过对腔有效折射率进行非周期性图案化实现了模式光谱的光谱滤波。通过选择间隔为基本模式间隔两倍的六个模式，在 100GHz 的重复率下获得了接近变换极限的 2ps 脉冲持续时间的脉冲输出。
