摘要: 本文采用含有轴向坐标参变量的标量波动方程来描写锥体光纤,通过一种简单的变换,将标量波动方程化为一阶微分方程组。用四阶龙格——库塔法的基尔改进式,计算了单模锥体光纤的传输特性。

Abstract: A Scalar wave equation with an aix direction variate z is used to describe a single-mode taper fiber, and the scalar wave equation is changed to one-order differential equations group by a Simple transform. The quartic Runge-kutta Method improved by Gill is used to Calculate the propagation Characters of a Single-mode taper fiber.

Key words: optical fiber, taper fiber, propagation property
