摘要
为降低传输损耗,在太赫兹波段采用具有低吸收损耗的环烯烃共聚物作为基质材料,设计了一种太赫兹光子晶体光纤。通过全矢量有限元法模拟仿真,对光子晶体光纤的损耗和频率的关系进行了分析计算。结果表明,这种光纤在太赫兹频段具有良好的传输特性,大大优于传统的金属波导,且该类型光纤还具备良好的弯曲性能,在太赫兹频段具有重要应用价值。
A terahertz Photonic Crystal Fiber（PCF） made of Cyclic-Olefin Copolymer（COC） with low absorption loss in terahertz band is designed to reduce the transmission loss. By full vector finite element method, the loss of terahertz PCF versus frequency is simulated and analyzed. Results show that the proposed fibers have much better transmission properties than metallic waveguides in terahertz band. Along with the fine flexibility to bend, they are of great importance in terahertz applications.
