摘要
Bragg光纤是一种具有全向反射光子带隙的新型微结构光纤。分析了无限包层Bragg光纤中的模式,在此基础上对有限包层Bragg光纤中传输的模式进行了分类。通过对比研究无限包层Bragg光纤中的模式,把有限包层Bragg光纤的模式分为准导模、PML模和泄漏模,并对上述模式的特性进行了简要分析。
Abstract
Bragg fiber is a new kind of microstructure fiber with wide-or omni-directional bandgap guidance.Themode of Bragg fibers with infinite number of H/L layersis analyzed,which paves the way for the classification of Bragg fi-bers with finite number of H/L layers.In comparative study of the properties of Bragg fibers with infinite number of H/L layers,three modes can be classified in Bragg fibers with finite number of H/L layers in terms of the mode of spectrum.They can be identified as quasi-guided mode,leaky mode and PML mode,and their different properties are analyzed.
