摘要
布拉格光纤是由在径向折射率呈周期分布的多层介质圆环构成的一种光纤。由于多层的几何结构特征,布拉格光纤表现出与普通光纤不同的色散特性。引入等效折射率法(EIM)结合多层光波导理论来分析布拉格光纤,对于布拉格光纤的色散特性进行了深入的分析,得到了布拉格光纤色散的比例性质(scaling properties),并举例说明利用波导色散与结构参量的关系,通过调整布拉格光纤的结构参量,灵活地设计其色散特性。
Abstract
Bragg fibers are a kind of fiber formed by multilayer concentric cylinders with period index distribution in the radial. Since Bragg fibers have multilayer geometric characteristics, their dispersion properties are special. The effective index method (EIM) combined with multilayer waveguide theory is introduced to analyze the dispersion properties in detail, and also the scaling properties for Bragg fiber′s waveguide dispersion are gotten here. Examples are shown at last to illustrate how to design the chromatic dispersion through adjusting the Bragg fibers′ structure parameters based on the relations between the waveguide dispersion and the structure parameters.
