本文对两种不同类型的抑制耦合（IC）波导空芯光纤的保偏特性以及光纤弯曲的影响进行了全面的分析。观察到由于光纤的正交偏振LP01模的传播常数失配而引起的入射线偏振态的相移引起的退化。理论上预测了这种效应，并与数值模拟和实验结果相证实。它示出的相移增强的光纤的弯曲半径的减少，但可以规避定向注入光束的偏振平行或垂直于弯曲的平面。
We report on a comprehensive analysis of the polarization-maintaining (PM) behavior of two different kinds of inhibited-coupling (IC) guiding hollow-core fibers and the influence of fiber bends. A phase shift induced degradation of the incident linear polarization state was observed due to a mismatch of the propagation constants of the orthogonally polarized LP01-modes of the fiber. This effect was predicted theoretically and is corroborated with numerical simulations and experimental results. It is shown that the phase shift is enhanced by a reduction of the bending radius of the fiber but can be circumvented by orienting the polarization of the injected beam either parallel or perpendicular to the plane of bending.
