本文结合微扰论，利用射线解法计算了自聚焦光纤的模间色散，结果与基于电磁场理论的ＷＫＢ法的结果完全一致。本文还指出了传统射线解法得不到正确结果的原因所在。
In this paper, we combine the perturbation theory and the ray solution to calculate the mode dispersion of the self-focusing fiber. The result is in good agreement with the WKB method based on the electromagnetic field theory. This article also points out the reason why the traditional ray solution can not get the correct result.
