Abstract

We established a novel Zeonex single-mode, porous core fiber for guiding THz waves. Full-vector FEM with layer boundary conditions that are perfectly matched has been used to investigate in addition to the wave guiding characteristics, birefringence, core power fraction, dispersion, confinement loss, effective material loss and the fibers' modality-effective surface area. A cyclo-olefin polymer (COP) based material, trade name Zeonex, was used for its special advantages as background material such as lower specific gravity, chemical resistance at lifted temperature, higher straightforwardness, lower melt flow index etc. over other materials. The loss count that we got was very low as EML is 0.03 cm−1and confinement loss is less than 107. Higher birefringence and flattened dispersion also have been achieved for this design. The Porous core fiber can be manufactured using existing fabrication technology and can be used in many applications at a negligible absorption loss within the terahertz frequency range.
利用Zeonex设计太赫兹区多孔芯光纤
我们建立了一种新的Zeonex单模多孔芯光纤,用于引导太赫兹波。采用层边界条件完全匹配的全矢量有限元法研究了光纤的导波特性、双折射率、芯功率分数、色散、约束损耗、有效材料损耗和光纤的模态-有效表面积。一种环烯烃聚合物(COP)基材料,商标为Zeonex,作为背景材料使用,具有比其他材料更低的比重、提升温度下的耐化学性、更高的直直性、更低的熔体流动指数等特殊优势。我们得到的损耗数很低,EML为0.03 cm−1,约束损耗小于107。该设计还实现了更高的双折射和平坦的色散。多孔芯光纤可以使用现有的制造技术制造,并且可以在太赫兹频率范围内以可忽略不计的吸收损耗用于许多应用。
