摘要

本研究提出了一种多孔纤芯光子晶体光纤(PC-PCF)的设计方案,该光纤由环状烯烃共聚物 Zeonex 与混合包层制成,用于低损耗太赫兹(THz)波传输。由于采用了圆形和椭圆形气孔组合,因此在 Dcore = 450 µm 和 f = 1 THz 时,材料吸收损耗非常低,仅为 0.045 cm-1。在 0.5-1.4 THz 的宽频率范围内,可获得 0.73 ± 0.13 ps/THz/cm 的平坦色散。此外,还分析了磁芯直径和其他关键特性的频率响应,如归一化频率(V 参数)、约束损耗、有效面积、非线性以及通过拟议 PC-PCF 不同部分的功率流百分比。与最先进的设计相比,我们的设计在损耗、色散和功率分数方面更胜一筹。我们提出的设计可以使用成熟的挤压工艺制造,并可用于长距离低损耗太赫兹(THz)通信。

Porous core fiber with hybrid cladding for ultra-flattened dispersion and low loss propagation of terahertz waves

This work proposes a design of a porous-core photonic crystal fiber (PC-PCF) made of a cyclic olefin copolymer, Zeonex, with a hybrid cladding for low-loss terahertz (THz) wave transmission. A combination of circular and elliptical air holes is employed, resulting in a very low material absorption loss of 0.045 cm-1 at Dcore = 450 µm and f = 1 THz. A flat dispersion of 0.73 ± 0.13 ps/THz/cm is obtained for a broad frequency range of 0.5–1.4 THz. Core diameter and frequency response of other key features such as normalized frequency (V-parameter), confinement loss, effective area, nonlinearity and the percentage of the power flow through different sections of the proposed PC-PCF are also analyzed. Comparing to state-of-the-art, our design is superior in terms of loss, dispersion and power fraction. Our proposed design can be manufactured using the established extrusion process and be used for long distance low-loss Terahertz (THz) communication.
