基于微腔效应增强单层二硫化钨光吸收

提出基于金属薄膜-分布式布拉格反射器微腔效应增强单层二硫化钨光吸收的多层薄膜结构。运用光学传输矩阵理论研究了其输运特性,发现由于金属薄膜-分布式布拉格反射器的微腔效应,在间隔层和覆盖层之间形成电场强度极大值,有效促进入射光与单层二硫化钨的相互作用。综合优化金属层、间隔层和覆盖层厚度,单层二硫化钨在6

Tunable ultra narrow band optical filter based on a whispering gallery mode hybr

We demonstrate an ultra-narrow-band optical filter based on a hybrid-microsphere consisting of a coated SiO2 microsphere. As compared to the SiO2 micr

聊聊cleancode

clean code,顾名思义就是整洁的代码,或者说清晰、漂亮的代码,相信大多数工程师都希望自己能写出这样的代码。也许这是个千人千面的话题,每个工程师都有自己的理解。比如我,从一个天天被骂代码写得烂的人,逐渐学习成长,到现在也能写的出“人模人样”的代码来了。这期间算是积累了一点经验心得,想和大家分享

紧聚焦条件下的轴向双焦点波带片

基于紧聚焦条件下的矢量衍射理论推出了一个解析解形式的环半径公式,利用此公式设计得到的二元相位波带片可以使入射光的紧聚焦区域呈现轴向双焦点分布。并且,公式中的两个焦点的轴向距离和环半径直接相关,可以设计一系列的具有不同轴向距离的二元相位波带片,用来调制高数值孔径物镜,使其产生轴向可调的双焦点。以径向偏
