| 中文摘要 | an approximate analytical description for fundamental-mode fields of graded-index fibers is explicitly presented by use of the power-series expansion method, the maximum-value condition at the fiber axis, the decay properties of fundamental-mode fields at large distance from the fiber axis, and the approximate modal parameters u obtained from the gaussian approximation. this analytical description is much more accurate than the gaussian approximation and at the same time keep the simplicity of the latter. as two special examples, we present the approximate analytical formulas for the fundamental-mode fields of a step profile fiber and a gaussian profile fiber, and we find that they are both highly accurate in the single-mode range by comparing them with the corresponding exact solutions. |
