论文摘要
平均时间（PT）对称性是一种在激光器中获得单模式操作的新方法，主要是微环激光器。在这项研究中，我们提出并在实验上证明了电泵的PT对称Fabry-Perot（FP）激光器，该激光器可以与模式选择一起使用。提出的激光器可以通过对两个FP谐振器中增益和损失之间的相互作用的电气操纵来实现PT对称条件。单个模式激光在1574.6nm处显示为20.81db sidemode抑制比。
Parity-time (PT) symmetry is a new method to get single mode operation in lasers, mostly, micro-ring lasers. In this study, we propose and experimentally demonstrate an electrically pumped PT symmetric Fabry-Perot (FP) laser which can work with a mode selection. The proposed laser could achieve the PT symmetric condition by an electrical manipulation of the interplay between gain and loss in two FP resonators. The single mode lasing is demonstrated at 1574.6nm with a 20.81dB sidemode suppression ratio.
