摘要: 以环烯烃共聚物（cyclic-olefin copolymer，COC）材料为基质，设计、制造了一种空芯多孔包层太赫兹（THz）纤维。利用comsol 软件模拟了芯径为6 mm 的光纤在0.2~1.5 THz 波段的损耗特性，结果表明：在0.85~1.5 THz 波段存在多个低损耗频带，而且在0.85~1.1 THz 波段有低于3 dB/m 的三个窗口；特别是在0.99 THz，损耗达到0.208 dB/m。芯径为3 mm、4.8 mm 和6 mm 的光纤在0.8~1.5 THz 波段的损耗特性对比分析表明：该COC 微结构多孔包层空芯纤维的损耗随着光纤外径的增加而减小。把设计的太赫兹纤维外径放大7 倍达到7 cm，据此设计制造了光纤预制棒成型专用模具。借助热挤出成型方法得到了结构完整、孔洞表面光滑，长度为22 cm 的空芯多孔包层预制棒。利用该实验室独有的微结构光纤拉丝塔，成功获得了微结构保持完好的光纤样品。损耗分析结果表明：6 mm 芯径的光纤样品在1.27 THz 的平均损耗为2.175 dB/m，与该频率的理论损耗（1.95 dB/m）接近。

Abstract: A hollow-core porous microstructured terahertz fiber based on Topas cyclic-olefin polymer (COC) was designed and manufactured. The loss characteristics of an optical fiber with outer diameter 10 mm was simulated using comsol software in the 0.2-1.5 THz band. There are several low-loss bands in the 0.85-1.5 THz, and there are three windows in which the loss is lower than 3 dB/m in the 0.85-1.1 THz band, the loss is about 0.208 dB/m especially in the 0.99 THz. By comparing the loss characteristics of the fiber with core diameter of 3 mm, 4.8 mm and 6 mm in 0.8-1.5 THz band, the loss was reduced with increasing the diameter. The outer diameter of designed THz fiber was enlarged to 7 cm, and a dedicated mold was designed for manufacturing preform. A 22 cm long THz fiber preform with a standard structure and smooth surface was manufactured by the hot extrusion molding method. Finally,through the laboratory's unique draw tower, the terahertz fiber of the core diameter of 3 mm, 4.8 mm and 6 mm were manufactured. The loss analysis result show that the average loss of the fiber with core diameter of 6mm is 2.175 dB/m in 1.27 THz and it is near the theoretical loss (1.95 dB/m).
