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有关,并给出了条件表达式及其详细说明。In order to minimize the powerloss grade waveguide and band waveguide without increasing the dimension, 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 expressed in math formula.
