摘要

对椭圆嵌套椭圆负曲率空心芯光纤在太赫兹区域的光损耗进行了数值计算。对所有光纤的主要设计参数进行了迭代优化，在0.55 THz下，约束损耗和总损耗分别低至$2.79 \乘以10^{-5}\ mathm {~dB} / \ mathm {m}$和$0.015 \ mathm {~dB} / \ mathm {m}$。对该设计的单模光导进行了研究，并计算出了3000左右的高阶模消光比。

Elliptical cladding elements in negative curvature hollow-core fiber for low-loss terahertz guidance

Optical losses of ellipse-nested elliptical negative curvature hollow-core fibers are numerically presented for the terahertz region. Primary design parameters of all fibers were iteratively optimized and confinement and total losses as low as $2.79 \times 10^{-5} \mathrm{~dB} / \mathrm{m}$ and $0.015 \mathrm{~dB} / \mathrm{m}$ were achieved at 0.55 THz, respectively. Single-mode light guidance of the proposed design was investigated and a higher-order mode extinction ratio of around 3000 was calculated.
