The Fabrication, Experiment and Application Research of the Novel Fiber Grating

Abstract

本文主要以长周期光纤光栅(LPFG:LongPeriodFiberGrating)和布拉格光纤光栅(FBG:FiberBraggGrating)作为研究对象,在光纤光栅的制作、应用、模式耦合和新器件的开发等方面做了大量、细致的研究。首先,根据长周期光纤光栅的模式耦合理论,用数值分析的方法来模拟其在不同参数条件下的传输谱线,并与实验结果对照,证明计算结果的有效性。同时,基于测量布拉格光纤光栅的传输谱线,通过数值计算布拉格光纤光栅的色散方程并寻找满足布拉格相位匹配条件的解来得到光纤光栅的纤芯直径和折射率,计算结果在误差范围内符合实际情况,该方法为测量阶跃型光纤光栅参数提供了一种新的途径。在数值计算...The dissertation mainly focuses on the LPFG (Long Period Fiber Grating) and FBG (Fiber Bragg Grating).
