摘　　要：分析得到了横向电场分量和磁场分量所满足的耦合方程,对于介质折射率的不连续处,采用严格的边界条件来处理。基于全矢量模型,使用有限差分法编写了复模式的求解器,并将其应用于Bragg光纤的模式求解和分析。绘制出了Bragg光纤模式谱图,分类分析了在无限包层情况下Bragg光纤模式的基本特性。The coupling equations which satisfy the transverse field components are obtained,and rigid boundary condition is used to solve the discontinuity of medium refractive index.The complex pattern equation solvers are gotten by using full vector model and finite difference method.The solver is used to analysis the modal of Bragg fiber.After painting the mode-spectrogram of Bragg fiber,the basic properties of the Bragg fiber with unlimited cladding are classified and analyzed.
