摘要/Abstract

摘要：应用全矢量有限元方法，分析了高折射率芯Bragg光纤的气体传感特性，通过计算Bragg光纤的结构参数、传输光波长与其传感灵敏度之间的关系，结果发现：同等条件下，传输波长越长，高折射率纤芯半径越小，高折射率介质折射率越低，高折射率芯Bragg光纤的传感灵敏度则越高.

Abstract: The gas sensing property of high-index-core Bragg fiber is investigated in this paper via a powerful full-vector finite element method.Based on the simulation and analysis,the relationship between the gas sensing property of high-index-core Bragg fiber and the fiber structure parameters,as well as the wavelength,has been gained,which shows the gas sensing property of the fibers increases with the decrease of the fiber’s radius and refractive index,but it increases with the increase of the wavelength.These results will be helpful to the design of high performance one-dimensional microstructured gas or liquid sensing fibers.

Key words: guided wave and fiber optics, Bragg fibers, finite element, fiber sensor
