光纤光栅的特性分析 摘 要 光纤光栅是最近几年发展最为迅速的光纤无源器件之一。自从1978年K.O.Hill 等人首先在掺锗光纤中采用驻波写入法制成世界上第一只光纤光栅以来，由于它具有许多独特的优点，因而在光纤通信、光纤传感等领域均有广阔的应用前景。随着光纤光栅制造技术的不断完善，应用成果的日益增多，使得光纤光栅成为目前最有发展前途，最具代表性的光纤无源器件之一。由于光纤光栅的出现，使许多复杂全光纤通信和传感网成为可能，极大拓宽了光纤技术的应用范围。 本文的研究内容将主要围绕光纤光栅的分类，均匀光纤光栅的特性，光纤光栅的理论分析，均匀光纤光栅的Matlab仿真，以及均匀光纤光栅反射谱的分析来展开分析和论述。首先本文会对光纤光栅的分类进行了解，重点了解均匀光纤光栅的基本性质和结构。对光纤光栅的理论进行分析，然后通过对光纤光栅的耦合模拟理论，光纤光栅的傅立叶变换法，光纤光栅的传输矩阵法的公式的推导掌握光栅光纤的基本理论，熟悉均匀光纤光栅的模型。改变公式中不同因素的数值，通过编写Matlab程序，分析运行结果。最后通过Matlab的运行图谱分析各不同因素对均匀光纤光栅反射谱的影响。 光纤光栅；均匀光纤布拉格光栅；反射谱 Abstract Fiber grating is one of the most rapid passive optical fiber components in recent years. Since 1978, the year when K.O.Hill and others first used the standing wave writing way in the germanium-doped fiber and make the worlds first fiber grating, because of its?many unique advantages, the use of the fiber grating in optical fiber communications Fields and fiber optic sensor Fields are broad prospected. With fiber grating manufacturing technology continues to improve, and the outcome of the application increasing, the fiber grating has been one of the most promising and representative optical passive components. The emergence of fiber grating makes many of the complex all-fiber communications and sensor networks possible, which greatly widened the scope of application of optical fiber technology. This study will focus on the classification of fiber Bragg grating, the characteristics of uniform fiber Bragg grating, fiber grating theoretical analysis, uniform fiber Bragg grating simulation of Matlab, as well as the uniform fiber Bragg grating reflection spectrum analysis to analyze and address. This article will first of all, the classification of fiber Bragg grating to understand the situation, the focus of understanding of even the basic properties of fiber Bragg grating and structures. The theory of fiber grating analysis, and then through the coupling fiber grating simulation theory, fiber grating Fourier transform method, the fiber grating transfer
