摘　　要：将"双向迭代"、牛顿二次差商以及直接微分等分析手段有效地结合起来,形成一种被称为"微分迭代"的波导方程解析方法.该方法可根据任意光纤的剖面结构在计算机上精确模拟出光纤的能量场分布、波导色散、零色散波长和截止波长等参量.该解析法分别被用于三包层G.655光纤和五包层G.656光纤的波导分析,分析结果和实测值具有极好的一致性.A differential iteration solution is presented by combining the features of bidirectional iteration method, Newton＇s interpolation formula and direct differential method. The solution is used to solve the electric field distribution, chromatic dispersion properties and cutoff wavelength of fibers with arbitrary refractive index profiles. And the solution was used for waveguide analysis to G. 655 fiber with three claddings and G. 656 fiber with five claddings, and the result agrees well with the values by experimental measurement.
