運用一種簡單方法作光纖光柵之設計與分析

Abstract

本論文中我們利用L. Poladian在2000年6月發表之文獻中所提出重建光柵耦合係數的方法，作了四種設計例子，包括：無色散光柵、二階色散補償光柵、三階色散補償光柵、線性反射率光柵；並探討影響設計的參數，以及將最小相位的觀念應用在反射率的設計上。

In this thesis, we use the method proposed by L.Poladian in the June issue of Optics Letters to reconstruct the coupling coefficient of Bragg fiber gratings. We calculate and analyze four types of reflection coefficients using this tool. There are dispersionless reflectivity gratings, dispersion compensation gratings, dispersion compensation gratings and linear reflectivity gratings. Through these designs we discuss some parameters closely related to the characteristics of FBGs. And we also use the concept of minimum phase to the reflection coefficients.
