摘要

本文提出了一种适用于太赫兹传输的新型多孔核光子晶体光纤(PCF)，其在太赫兹窗口处具有极低的材料吸收损耗。采用有限元方法研究了多孔芯被具有六角形气孔的致密包层结构包围的聚丙烯腈纤维的性能。仿真结果表明，在1太赫兹的工作频率下，有效材料损耗(EML)可达到~ 0.028 cm−1，仅为Topas体材料损耗的12.5%。此外，在1太赫兹下获得的约束损耗为0.0005 cm−1，相对较低，平坦色散分布接近于零，为0.196±0.183 ps/THz/cm，这是长距离宽带太赫兹传输的重要特征。

Low loss porous-core photonic crystal fiber for long-haul broadband THz transmission

This paper presents a novel porous-core photonic crystal fiber (PCF) having extremely low material absorption loss at terahertz window suitable for THz transmission. Finite element method (FEM) is used to investigate the properties of the proposed PCF with a porous core surrounded by a compact cladding structure having hexagonal air holes. Simulation results reveal that effective material loss (EML) of ∼ 0.028 cm−1 can be achieved at operating frequency of 1 THz which is only 12.5% of the bulk material loss of Topas. Additionally, the confinement loss of ∼ 0.0005 cm−1 is obtained at 1 THz which is relatively low with a nearly zero flat dispersion profile of 0.196 ± 0.183 ps/THz/cm which are significant features for long distance broadband THz transmission.
