设计了一种低损耗高非线性的碲化物PCF（光子晶体光纤）。采用分布傅里叶算法求解非线性薛定谔方程,数值模拟了基于PCF的中红外波段SC（超连续谱）的产生与控制。分析了PCF参量及泵浦光源参数对SC的影响,得出SC宽度和平坦度随PCF长度、色散参量以及泵浦脉冲峰值功率、初始宽度的变化规律。仿真结果表明,中心波长为2μm、脉冲峰值功率为20kW、脉冲宽度为100fs的泵浦光在PCF中传输15cm时,SC谱宽可达1 3303 450nm,且具有良好的平坦度。

文章在设计低损耗太赫兹光子晶体光纤的基础上,利用光学设计软件Zemax设计了一种焦距为24.80mm、厚度为2.00mm、有效孔径为6.25mm的Topas COC（环烯烃共聚物）太赫兹单透镜。该透镜能有效提高太赫兹光束与波导的耦合,耦合效率可达75.01%。运用Zemax和Matlab软件分析了太赫兹波导与耦合系统在对接出现误差情况下对耦合效率的影响,并分别给出了存在横向偏差与角度偏差情况下的耦合效率变化曲线。研究结果可为太赫兹传输技术提供理论参考。

Atherosclerosis (As) is a focal vascular disease that closely related to many injury factors such as endothelial inflammation, oxidative stress, and shear stress. More and more studies have shown that the risk of As is higher in a variety of non-cardiovascular diseases. This review summarizes the mechanism of As in respiratory system diseases, digestive system diseases, urinary and reproductive system diseases, autoimmune diseases and metabolic diseases from the perspective of endothelial inflammation and oxidative stress.
