Abstract

In this research, we propose a novel hollow-core anti-resonant fiber structure designed to enhance light confinement and reduce losses. Our simulation results indicate that the LP01 mode loss is reduced to 1.807 × 10⁻⁶ dB/km at a wavelength of 1.52 μm, representing an extremely low confinement loss. Additionally, our model exhibits strong bending resistance, maintaining a bending loss of 4.81 × 10⁻⁵ dB/km at a wavelength of 1.55 μm and a bending radius of 6 cm. The dispersion is also maintained at 1 ± 0.7 ps/(nm·km), ensuring low dispersion characteristics. These features suggest its potential for applications in hollow-core fiber-based low-latency telecommunication systems.

摘要

在本研究中，我们提出了一种新型的空心反谐振光纤结构，旨在增强光限制并降低损耗。我们的模拟结果表明，在波长为1.52μm时，LP01模式损耗降低至1.807×10⁻⁶dB/km，这代表着极低的限制损耗。此外，我们的模型表现出很强的抗弯曲能力，在波长为1.55μm、弯曲半径为6cm时，弯曲损耗保持在4.81×10⁻⁵dB/km。色散也保持在1±0.7ps/(nm·km)，确保了低色散特性。这些特性表明其在基于空心光纤的低延迟电信系统中的应用潜力。
