摘　　要：摘用束传播 自由空间辐射模 (BPM F-SRM)混合法计算了SOI脊形波导和光纤耦合时的透射率,提出计算反射率的积分公式 将该混合法和一般FSRM、菲涅尔公式 重叠积分法的计算结果相比较,提出只有在弱导条件下,传统的菲涅尔公式法和重叠积分法才可以同时使用.With hybrid method of BPM and FSRM, the power of transmission was calculated in the case of SOI Rib Waveguide-to-Fiber coupling. A simple integral formula was developed to work out the reflectivity. Based on the results acquired with the hybrid method, normal FSRM methods and Fresnel equation-overlap integral method, it was deduced that Fresnel equation method and overlap integral method can be used together only when the two waveguides on the each side of disconnection facet are weakly-guided.
