Research progress of terahertz fiber waveguide

实现太赫兹波的低损耗、柔性传输是解决太赫兹设备轻量化、便携化的一个核心途径。本文综合分析了近年来太赫兹纤维波导技术的研究历程,把纤维波导的研究分为原始材料的选择和挖掘、纯材料的结构设计与加工、拉伸超材料波导的设计与加工3个阶段,并对各阶段的典型研究成果、优缺点及应用性进行了总结。最后,展望拉伸超材料将成为近期太赫兹纤维波导技术研究的新方向,有望实现太赫兹波的低损耗、柔性化、低廉性传输。

Achieving low-loss and flexible transmission of terahertz wave is the key approach todevelop light and portable terahertz equipment. Research progress of terahertz fiber waveguide technologyis overviewed. The whole progress is divided into 3 stages described as selection and exploitation oforiginal materials, design and fabrication of pure materials, design and fabrication of drawn meta-material.Then the achievements, advantages and disadvantages, and applications of these stages are analyzed.Finally, it is prospected that the drawn meta-material will be a novel research direction, and thehigh-transmission, flexible and low-cost terahertz fiber waveguide is expected to be fabricated in thefuture.
