摘要

摘要该研究调查了在亚纳秒电流脉冲泵浦条件下工作的基于双不对称异质结构的光隔离单模激光器的微条纹条。对于具有不同发射孔填充密度的微条纹条，各种条纹导通的时间延迟色散效应得到了证实，最大差异可达 50 ps。所开发的微带条设计显示出稳定的零模激光。由 10 条宽度为 6 μm、条纹周期为 20 μm 的条纹组成的微条纹条在 0.4 ns 电流脉冲泵浦下可产生峰值功率为 3 W、持续时间为 140 ps 的脉冲。

Abstract

The study investigates microstripe bars of optically isolated single-mode lasers based on heterostructures with double asymmetry, operating under sub-nanosecond current pulse pumping conditions. For microstripe bars with different filling densities of the emitting aperture, the effect of time delay dispersion of various stripes’ turn-on is demonstrated, with a maximum difference up to 50 ps. The developed microstripe bar designs demonstrate stable zero mode lasing. The microstripe bar consisting of 10 stripes with a 6 μm width and a stripe period of 20 μm demonstrates pulses with a peak power of 3 W and a duration of 140 ps under 0.4 ns current pulses pumping.
