2 、详细阐述了长周期光纤光栅的模耦合理论和传输矩阵理论，并进行了模拟计算。 - When the isotropic waveguide is under the isotropic disturbances , the coupling term due to polarization , which is presented in the coupled - mode theory of the wei - ping huang , is n ' t included in this rigorous vectorial coupled - mode theory , exactly , the rigorous vectorial cmt does n ' t contain the coupling term due to polarization which is include in the scalar coupled - mode theory because this term is counteracted with the other coupling term neglected under weakly guiding approximation . as for anisotropic disturbances , we get the coupled - mode equations with arbitrary dielectric tensors . from them , we obtain the coupled - mode equations of the slowly varying term c ( z ) which is more simplicity
当受到各向同性微扰时，我们发现严格的矢量理论所得到的耦合系数表达式中并不包括wei - pinghuang的理论中的偏振耦合项，更确切的说，偏振耦合项正好与因弱导近似而忽略的项相抵消，这就是标量理论所得到结果(有偏振耦合项)与矢量理论在标量近似下的结果(不含偏振耦合项)不一致的原因所在；当各向异性微扰时，我们得到了包含微扰介电张量各个分量的横电磁场耦合波方程，讨论了微扰介电张量各个分量对耦合的影响，而且从横电磁场耦合波方程出发得到了形式更加简单的只含有横电场系数的缓变分量c _ ( z )的耦合波方程和耦合系数表达式，并以弱导近似下的单模光纤两正交偏振模耦合为例对耦合系数在不同条件下的取舍做了定性的分析。 - We studied the multimode coupling matrix of the key waveguide discontinuity , waveguide step , with the modal fields expansions in waveguides . and obtained the relations with the multimode coupling matrix , the generalized admittance matrices and the generalized scattering matrices . we have compiled some subroutines in fortran 95 programming language to compute the multimode coupling matrix , admittance matrices , scattering matrices and their operates with each other
并利用fortran95程序设计语言编写了用来计算波导阶梯的多模耦合矩阵、多模耦合矩阵与广义导纳矩阵的级联、广义导纳矩阵之间的级联以及广义导纳矩阵和广义散射矩阵之间的互相换算等的矩形波导平面不连续性模式分析的子程序。 - In addition , it was the sign of the initial amplitude growth rate , not the manner of the interface motion that determined whether the amplitude could increase . at weakly nonlinear stage , mode - coupling equations were derived in cylindrical and spherical geometries . it showed that the nonlinear terms were inversely proportional to the position of the interface in cylindrical and spherical geometries
在弱非线性阶段，推导了柱和球几何中模耦合方程，结果表明：非线性作用项反比于界面的位置，界面的位置越小，非线性作用越强，反之越弱；同时柱几何中模耦合方程的解表明，在收缩几何中，扰动在界面两侧的发展是不对称的，在弱非线性阶段，不稳定性向内发展的部分受到惯性力的挤压，而向外发展的部分受到惯性力的拉伸。
