中文摘要光纤光栅因为其丰富的选频特性,优良的动态调谐性能,低的插入损损、偏振无关以及与光纤的天然兼容性而成为未来全光通信和光传感领域引人注目的一种光子器件。本论文从光纤通信网络的发展和应用需求出发,围绕可调谐光纤光栅这一主题,对基于弹性梁的光纤光栅调谐方案进行了深入的理论和实验研究。在分析和模拟弹性梁应力应变分布的基础上,对弹性梁调谐机构进行了优化设计,实现了弹性梁上的纯弯曲变形,并采用基于纯弯曲梁的光纤光栅无啁啾调谐方法,在实验上获得了较好的结果。
英文摘要Now, fiber Bragg gratings (FBGs) have become a notable photonic devices in future all-optical network and fiber sensor netwo氏for its abundant frequency selection characteristics, excellent tuning performances, low insertion loss, low polarization dependence, naturally compatibility with fiber. The schemes of FBG tuning based on elastic beams have been investigated deeply both in theory and experiment, according to the practical application of optical communication and fiber sensing network. The optimization designs for tuning structure of elastic beams have been made based on the analysis of stress and strain distribution in the beam. A tuning structure of pure bending characteristics has been realized to demonstrate the chirp-free tuning of FBCx The main content of this thesis include following aspects.
