用矩阵法计算任意折射率剖面单模光纤的传输参量

Calculation of the propagation parameters of arbitrary index profile single mode fiber by using the matrix method

用拉盖尔－高斯级数逼近单模光纤中横场，不多的几项即可达到很高的精度。文中给出了该方法的理论推导，并用相应的程序进行了验证。该法对任意的圆对称折射率剖面光纤计算传输常数和色散能够得到满意的结果。

High accuracy is achieved by using a few terms of Laguerre-Gaussian series to approxmate the transverse field in the single mode fiber.The theory formulation is present,and verified by associating programs.Good result is achieved for the propagation constants and chromatic dispersion of arbitrary index profile single mode fiber.
