摘要
由于锥形光纤具有独特的几何结构特征,从而引起了光纤的归一化频率、有效横截面积、光强密度、群速度色散及非线性系数等许多光学性质的变化。介绍了近年来得以广泛研究和应用的锥形光纤技术,分析了其具备的特殊功能,包括光功率在锥区的重新分布、干涉滤波、脉冲频率展宽等,并探索了其在光纤器件制作、传感技术、超连续谱产生等诸多领域的应用。
Due to its special geometric structure characteristics of the tapered fiber,many optical properties ineluding the normalized frequency, the effective cross-sectional area, the density of light intensity, group velocity dispersion, nonlinear coefficient in optical fiber have been changed. This paper introduced the technology of ta- pered fiber widely investigated and used in recent years and analyzed its special functions, such as redistribution of optical power in tapered region, interference filter, pulse frequency broadening, etc. In addition, we explored its wide applications in optical fiber devices making, sensor technology, generation of super-continuum spectrum and many other fields.
