摘要

我们研究了宽带InGaAs量子点激光器在被动调q模式下的性能。由于载流子通过润湿层储层传输而产生的点耦合程度对脉冲特性有很大影响。如果这种点间的相互作用被去除，q开关就不能再实现。

Self-sustained Q-switching in InGaAs quantum dot lasers

We investigate the performance of wide-band InGaAs quantum dot lasers operated in a passively Q-switched mode via the use of saturable absorber sections. The pulse characteristics are strongly influenced by the degree of dot coupling due to carrier transfer via the wetting layer reservoir. If this inter-dot interaction is removed Q-switching can no longer be achieved.
