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

用有限差分光束传播法（FD BPM）进行了模拟分析

发现过渡波导形状的选取与坡度和曲折角存在条件关系

并给出了条件表达式和详细说明.

Abstract

In order to minish the powerloss without increasing the dimension of grade waveguide and band waveguide

four shape functions of transitional waveguide are proposed and analysed by the finitedifference 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.
