超高速锁模激光器、相干频率梳状激光器和单模窄线宽分布反馈激光器在大容量相干光超信道通信、光时钟、光传感和光采样等方面有着广泛的应用。量子点是实现上述应用的关键技术。因此，QD半导体锁模激光器和单模DFB激光器应运而生。该激光器具有低阈值、低芯片、低线宽增强因子、窄线宽等特点。我们将利用所要求的表征平台研究创新的量子点锁模激光器、相干频率梳状激光器和超窄线宽DFB激光器。

Ultra high speed mode-locked lasers, coherent frequency comb lasers and single-mode narrow linewidth DFB lasers have many applications such as high capacity coherent optical superchannel communications, optical clocking, optical sensing and optical sampling. Quantum dot (QD) is the key technology to realize the above applications. Therefore, QD semiconductor mode-locked lasers and single-mode DFB lasers are emerging. The lasers have low threshold, low chip, low linewidth enhancement factor, and much narrow RF linewidth etc. We are going to use the requested characterization platform to investigate innovative quantum dot mode-locked lasers, coherent frequency comb lasers and ultra-narrow linewidth DFB lasers.
