微结构光纤的横截面具有按照一定规律分布的微结构(通常是微米尺寸的空气孔),且沿光纤轴向保持结构不变,这些微结构将光约束在光纤的纤芯中传导.微结构光纤不仅本身是一种优秀的波导介质,而且分布在其包层、纤芯的微米尺度空气孔也成为材料集成的天然通道.因此,微结构光纤是构造纤内实验室的理想载体.首先简单介绍微结构光纤的分类和传导机制,然后结合作者课题组近几年的研究工作,综述基于微结构光纤的纤内实验室技术的工作原理、实现方法和主要应用.
The cross-section of a microstructured optical fiber (MOF) has a microstruc- ture, usually micron-sized air holes, distributed according to a certain law. It remains unchanged Mong the fiber axis. These air holes limit light in the fiber core. MOF is an ex- ceUent waveguide medium, and the micron-scMe air holes distributed in its cladding or core can act as a channel of material integration. Therefore, MOF is an ideal carrier for con- structing lab in fiber. In this paper, we discuss the classification and the light conduction mechanism of MOF and, based on the recent research in the authors' group, summarize the principle, methods of implementation and main applications of lab in fiber technology based on MOF.
