Abstract

Bragg fiber is a new kind of microstructure fiber with wide-or omni-directional bandgap guidance.The mode of Bragg fibers with infinite number of H/L layersis analyzed,which paves the way for the classification of Bragg fibers 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.

有限H/L层布拉格光纤中模式的分类和性质

Bragg光纤是一种具有宽向或全向带隙引导的新型微结构光纤。分析了具有无限H/L层数的Bragg光纤的模态，为有限H/L层数的Bragg光纤的分类奠定了基础。在对具有无限H/L层数的Bragg光纤的特性进行对比研究时，根据光谱模式可以将具有有限H/L层数的Bragg光纤分为三种模式。将它们分为准导模、漏模和PML模，并分析了它们的不同性质。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
