摘要

本文提出了一种适用于太赫兹波传输的具有平坦有效材料损耗(EML)和近零色散平坦特性的超低损耗波导。提出了一种新型的气孔位置作为光子晶体光纤的设计。数值分析表明,在工作频率为1.0 THz时,EML为0.562 dB/cm,在1.0 - 2.0 THz波段,EML为0.57±0.0225 dB/cm。该多孔芯光纤在0.9太赫兹频率下的EML为0.473 dB/cm,约束和弯曲损耗可以忽略不计。该波导在1.2 ~ 2.0 THz频段内具有接近零的平坦色散,为0.7±0.3 ps/THz/cm。

Ultra-low loss THz waveguide with flat EML and near zero flat dispersion properties
This paper represents an ultra-low loss waveguide with flat effective material loss (EML) and near zero dispersion flattened properties suitable for THz wave transmission. A novel type of air hole position is proposed as the design of the photonic crystal fiber. Numerical analysis exhibits an EML of 0.562 dB/cm at the operating frequency of 1.0 THz and a flat EML of 0.57±0.0225 dB/cm from 1.0–2.0 THz band. The proposed porous core fiber shows a low EML of 0.473 dB/cm with negligible confinement and bending losses at 0.9 THz frequency. This waveguide also exhibits near zero flat dispersion of 0.7±0.3 ps/THz/cm in the frequency band from 1.2 to 2.0 THz.
