Analysis of Coupling Efficiency of TO-Packaged VCSELs
垂直腔面发射激光器的TO封装的耦合效率模拟分析

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.
