我们报告了具有内摆线形芯结构的七单元芯和三环包层大节距Kagome晶格空芯光子晶体光纤（HC-PCF）的制造。我们通过实验和理论上证明，这种纤芯形状的设计增强了纤芯和包层模式之间的耦合抑制，并在大于 200 THz 的传输带宽上提供了基线接近 180 dB/km 的光学衰减。该损耗值可与最先进的光子带隙 HC-PCF 相媲美，同时提供大约三倍的带宽和更大的模式面积。此外，它在损耗方面也优于传统的圆芯形 Kagome HC-PCF。这种新颖的（据我们所知）HC-PCF 的开发具有许多应用的潜力，其中大光带宽和低损耗的组合是先决条件。 (C) 2011 美国光学学会
We report on the fabrication of a seven-cell-core and three-ring-cladding large-pitch Kagome-lattice hollow-core photonic crystal fiber (HC-PCF) with a hypocycloid-shaped core structure. We demonstrate experimentally and theoretically that the design of this core shape enhances the coupling inhibition between the core and cladding modes and offers optical attenuation with a baseline of similar to 180 dB/km over a transmission bandwidth larger than 200 THz. This loss figure rivals the state-of-the-art photonic bandgap HC-PCF while offering an approximately three times larger bandwidth and larger mode areas. Also, it beats the conventional circular-core-shaped Kagome HC-PCF in terms of the loss. The development of this novel (to our knowledge) HC-PCF has potential for a number of applications in which the combination of a large optical bandwidth and a low loss is a prerequisite.
