基于有限差分光束传播法的过渡波导功耗分析
摘要
为了在既定尺寸下减小斜坡波导和弯曲波导的功耗
设计了4种过渡波导形状函数

Abstract
In order to minish the powerloss without increasing the dimension of grade waveguide and band waveguide
four shape functions of transitional waveguide are proposed and analysed by the finitedifference beam propagation method. Based on it
conditional relations between optimized transitional waveguide shape and the angle of transitional waveguide are found out and proposed in math formula.
