摘要
采用FRESNEL光学软件和MATLAB软件,详细分析了垂直腔面发射激光器的TO封装组件对耦合效率的影响.发现增加耦合透镜的折射率、减少管帽的高度和耦合透镜的尺寸可以提高耦合效率.
The dependences of TO-packaged VCSELs on packaging subassemblies are analyzed using FRESNEL and MATLAB softwares. It is found that the coupling efficiency can be improved by increasing the refractive index of the coupling lens and by decreasing the height of the TO-cap or the size of the coupling lens.
