Abstract

This is the first part of two papers where we propose and apply a methodology for confinement loss analysis in tube lattice fibers (TLFs). The methodology is based on azimuthal Fourier decomposition (AFD) of the fiber’s cladding and core modes along the perimeters of the cladding tubes composing. This technique, combined with coupled mode theory, constitutes an effective approach to gain insight in the inhibited coupling waveguiding mechanism and design, along with fiber non-idealities impact on confinement loss. In this part I, we describe the approach and apply it to loss analysis of ideal TLFs. The approach is then applied to the analysis of the effects of tube thickness variation in part II.

用于空芯管格光纤损耗分析的方位傅立叶分解法 I 部分:理想光纤
本文是两篇论文的第一部分,我们提出并应用了一种方法来分析管状晶格光纤(TLF)的约束损耗。该方法基于光纤包层和纤芯模式沿包层管周边的方位傅立叶分解(AFD)。这项技术与耦合模式理论相结合,是深入了解抑制耦合波导机制和设计以及光纤非理想状态对限制损耗影响的有效方法。在第一部分中,我们介绍了这种方法,并将其应用于理想 TLF 的损耗分析。然后在第二部分中将该方法应用于分析管厚度变化的影响。
