We characterized the reflectivity and the modal discrimination of intracavity reflectors (ICRs) with different numbers of slots and presented harmonic mode-locking operation of a monolithic semiconductor laser comprising a compound cavity formed by a single deeply etched slot ICR fabricated from 1.55 μm AlGaInAs strained quantum well material. Gaussian pulses were generated at a 161.8 GHz repetition rate with a pulse duration of 1.67 ps and a time-bandwidth product of 0.81.
我们描述了具有不同槽数的内腔反射镜（ICR）的反射率和模式鉴别，并展示了由单个深蚀刻槽 ICR 构成的复合腔构成的单片半导体激光器的谐波锁模操作，该 ICR 由 1.55μm AlGaInAs 应变量子阱材料制成。在 161.8GHz 的重复率下产生了高斯脉冲，脉冲持续时间为 1.67ps，时间带宽积为 0.81。
