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.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.
