摘要

设计色散平坦阶跃折射率光纤的双包层或W折射率剖面，使人们能够理解各种LP模式及其二维、径向、强度和振幅图。这种折射率曲线可以在入射高斯光束的芯半径和腰半径不同的值下获得较高的芯功率。本文对三种工作波长进行了比较研究。考虑光纤输入端的菲涅耳反射，色散平坦光纤在1550nm处芯内功率达到最佳(99.4%)。

Study of the linearly polarized modes and power analysis of double-clad refractive index profile of a dispersion flattened step index fiber

Design of double-clad or W refractive index profile of a dispersion flattened step index fiber which enables the understanding of various LP modes and their 2D as well as radial, intensity and amplitude plots. This index profile results in achieving high power in core for different values of core radius and waist radius of incident Gaussian beam. A comparative study is presented in this paper at three operating wavelengths. Optimal power in core (99.4 %) is observed at 1550nm for dispersion flattened fibers considering Fresnel reflection at the input end of the fiber.
