论文摘要
我们证明了如何将两个耦合相同的谐振器之间的增益损失对比的存在用作增强激光二极管的调制频率响应的新自由度。在InalgaAS/INP MQW P-I-N结构上制造了弯曲半径为50μm的电泵式微林激光系统。设备的室温连续波（CW）激光阈值电流为27 mA。通过调整两个耦合微孔中的注入电流水平之间的比率，我们的实验结果清楚地表明，带宽的改善高达是单个设备的基本共振频率的1.63倍。这与我们的速率方程仿真模型非常匹配。
We demonstrate how the presence of gain-loss contrast between two coupled identical resonators can be used as a new degree of freedom to enhance the modulation frequency response of laser diodes. An electrically pumped microring laser system with a bending radius of 50 μm is fabricated on an InAlGaAs/InP MQW p-i-n structure. The room temperature continuous wave (CW) laser threshold current of the device is 27 mA. By adjusting the ratio between the injection current levels in the two coupled microrings, our experimental results clearly show a bandwidth improvement by up to 1.63 times the fundamental resonant frequency of the individual device. This matches well with our rate equation simulation model.
