摘要:

建立了一个考虑腔效应和粒子数脉动效应的垂直腔面发射激光器慢光模型。通过数值计算和实验验证了探测信号功率、注入偏置电流和波长失谐量对群延迟的影响。在室温下,在波长为1.3 $μ$ m的激光器中,可以实现高达65 ps的群延迟和高达10 GHz的调制频率。我们的VCSEL器件最显著的特点是有源区的长度只有几个$μ$ m长。基于量子点VCSEL结构的实验参数,我们发现激光腔的共振效应对群延迟的增强起着重要的作用。

英文摘要:

We develop a simple model for the slow lights in Vertical Cavity Surface Emission Lasers (VCSELs), with the combination of cavity and population pulsation effects. The dependences of probe signal power, injection bias current and wavelength detuning for the group delays are demonstrated numerically and experimentally. Up to 65 ps group delays and up to 10 GHz modulation frequency can be achieved in the room temperature at the wavelength of 1.3 $μ$m. The most significant feature of our VCSEL device is that the length of active region is only several $μ$m long. Based on the experimental parameters of quantum dot VCSEL structures, we show that the resonance effect of laser cavity plays a significant role to enhance the group delays.
