This paper studies self-focusing optical fiber by wave motion optical method. The equation of electromagnetic energy flaw line of TE_0 mode is derived. The essence of phenomenon of self-focusing is represented. 本文采用波动光学的方法研究自聚焦光纤,导出了TE。模的电磁能流线方程,阐明了自聚焦现象的实质。 This paper treats the axisymmetric field distribution in a SELFOC fiber,and discusses the errors in Ref.[1].We point out that the axi- symmetric transverse components E of an axisymmetric mode can not be Cartesian components Ex or Ey,and can only be Cylindrical comp- onents Er or E_0.Hence,the governing equation of E shouldbe 1/r d/(dr)(r(dE)/(dr))+[ω~2*/c~2K-1/r~2-β~2]E=0 where term -E/r~2 can not be discarded for the beam launched centrally along the axis.The solution to the zeroth-order is found and expressed... This paper treats the axisymmetric field distribution in a SELFOC fiber,and discusses the errors in Ref.[1].We point out that the axi- symmetric transverse components E of an axisymmetric mode can not be Cartesian components Ex or Ey,and can only be Cylindrical comp- onents Er or E_0.Hence,the governing equation of E shouldbe 1/r d/(dr)(r(dE)/(dr))+[ω~2*/c~2K-1/r~2-β~2]E=0 where term -E/r~2 can not be discarded for the beam launched centrally along the axis.The solution to the zeroth-order is found and expressed by generalized Laguerre polynomials.The solution to the first-order approximation is found by the perturbation method. 本文研究了自聚焦光纤中的轴对称场分布问题,讨论了 Gambling 和 Ma-tsumura 文章中的错误。我们指出,轴对称电场横向分量 E 不可能是笛卡儿坐标分量 E_x 或 E_y,E 只可能是柱坐标分量 E_r 或 E_(?)。因此,E 的方程应该是1/r d/(dr)(r (dE)/(dr))+[w~2/c~2K-1/r~2)-β~2]E=0对于沿轴线中心射入的光束,上式中的-E/r~2项不应略去。本文求出了方程的零级解,它用广义拉盖尔多项式表示。本文并采用微扰法求出了方程的一级近似解。 This paper deals with the propagation characteristics and mode conversion of axisymmetric modes in an imperfect SELFOC fiber with longitudinal gradually varying dielectric constant K=∈/∈_o=K_o-K_2(z)r~2. This problem has been considered by Sodha and others but we point out that the solution obtained by them is incorrect since a term -ψ/r~2 was missed out from the wave equation they used. After supplying the missing term, we find the analytic solution which is expressed in terms of generalized Laguerre polynomials....
