摘要

本文提出了一种新型的负曲率空心光纤，用于近红外区域的低损耗传输。本文采用有限元模型，数值研究了由同心圆交错方形构成的包层结构对约束损失的影响。该设计有八个包层管，嵌套的元素放置在管的外缘。在1.3 ~ 1.65 μm范围内，交错方形芯光纤的约束损耗低至0.12 dB/km。非圆芯设计的损耗分布与圆芯设计相当，并且在1.55 μm处传输性能有所提高。所提出的设计可以有许多应用领域，如数据传输，非线性光学和生化传感。

Hollow-core optical fiber with eight-pointed star cladding structure for low-loss transmission in telecom bands

In this study, a novel negative curvature hollow-core fiber is proposed for low-loss transmission in the near-infrared region. We numerically investigate the effect of the cladding structure, which is formed of concentrically interlaced squares, to the confinement losses using the finite element modelling. The design has eight cladding tubes with nested elements placed to the outer edge of the tubes. The confinement losses of the interlaced square core fiber is calculated as low as 0.12 dB/km in the range of 1.3 to 1.65 μm. The loss profile of the noncircular core design is comparable with the circular cores, and have improved transmission performance at 1.55 μm. The proposed design can have numerous application areas such as data transmission, nonlinear optics and biochemical sensing.
