【摘要】 光纤Bragg光栅(FBG)重构算法逆向从光纤光栅的光学反射特性获得其结构特性,对于设计满足实际需求的光纤光栅具有重要意义。本文从耦合模理论和传输矩阵方法出发介绍了一种最简单的光纤光栅重构方法。该方法的有效性通过设计两种色散补偿器得以体现:第一种色散补偿器的色散值在3dB带宽内恒为17ps/nm,另一种则为具有线性色散斜率的色散补偿器。更多还原

【Abstract】 The approach of inferring the grating profile from its reflection spectrum is referred to as Fiber Bragg Grating (FBG) Synthesis Algorithm.Synthesis of FBG is of great significance for the design of special FBG to have desired characteristics.In this letter one synthesis method based on the coupled-mode theory and transfer matrix method is proposed,and its accuracy and efficiency are demonstrated through designing two types of dispersion compensators: constant dispersion coefficient with 17 ps/nm and linear dispersion slope coefficient compensators.更多还原
