双芯光纤的制作及应用研究

摘要

双芯光纤是一种极其重要的无源光器件，它在光通信及光传感等方向发挥了不可替代的作用。首先介绍了目前主要存在的几种双芯光纤的结构、分类及其最新的制作工艺，然后根据双芯光纤独有的结构特性及两芯子之间耦合特性所表现出来的光谱特性在光纤传感与光通信领域的应用进行了叙述，最后通过数据知识平台的结果展示了近10年来与双芯光纤相关的热词并分析了双芯光纤近十年的发展趋势及其发展前景%　　The twin-core fiber is a crucial passive optical devices, it has played an irreplaceable role in the ar⁃eas of the optical communication and optical sensing. Firstly, the structure, classification and the latest manufactur⁃ing technique of present fibers are introduced. And according to the special structure characteristic of twin-core fi⁃bers and the spectrum characteristic causing by the coupling characteristic between two cores, the application of twin-core fiber in the area of fiber sensing and optical communication are described. Lastly, the hot words corre⁃sponding to two-core fiber over the past decade are showed by the data knowledge platform. And the development trends and prospects of the twin-core fiber in future 10 years are analyzed.
