Abstract

A hollow-core anti-resonant fiber for the THz regime is proposed and demonstrated. The proposed fiber is the hexagonal core shape which is directly extruded using a conventional 3D printer. Experimental results show that by using cyclic olefin copolymer (COC), the proposed fiber design provides a low attenuation of ∼3 dB∕m at ∼ 0.86 THz and ∼15 dB∕m at ∼ 0.42 THz.

摘要

提出并展示了一种用于太赫兹波段的空心反谐振光纤。所提出的光纤为六边形纤芯形状，是使用传统3D打印机直接挤出的。实验结果表明，通过使用环烯烃共聚物（COC），所提出的光纤设计在约0.86太赫兹时提供约3分贝/米的低衰减，在约0.42太赫兹时提供约15分贝/米的低衰减。
