中文摘要： 太赫兹系统的紧凑化、轻量化、柔性化以及低成本化的实现有待类似于光波导技术的太赫兹波导系统的问世。太赫兹波导系统的关键技术之一是低损耗的波导元件制造技术。本申请拟开展用于太赫兹波传输的聚合物太赫兹波导管（THZ pipe）、聚合物太赫兹纤维（THz fiber）的设计与制造技术研究。拟以在可见光区、太赫兹区透明的新型聚合物材料TopasCOC为基质，设计满足不同太赫兹系统需求的THz pipe \THz fiber。在完成两种THz waveguide结构设计的基础上，研究制造过程的各个关键技术：预制棒尺寸与高精度模具设计制造、预制棒制造技术、预制棒拉伸技术中的关键科学问题，寻求所设计光纤的几何尺寸、有序度、周期性得到有效控制的条件。在攻克制造技术难点的基础上，制造出两种不同结构的低损耗太赫兹波导，为构筑新一代轻量、紧凑、柔性、低价格太赫兹系统提供技术支撑。

英文摘要： Researchs on Terahertz technology has experienced dramatic growth recently in both technical achievement and commercial implementation. The growth is application driven, with interest from various fields such as chemical and astronomical spectroscopy and sensing, medical and biological imaging and analysis, defense and security screening, communication networks and radars, etc. Many of these applications, however, utilize free-space propagation, resulting in weak beam confinement and vulnerability to environmental fluctuations. Focal spot size is diffraction limited and relatively large for the wavelengths of interest, which inconveniently requires large sample areas in material characterization applications and makes system miniaturization challenging. THz waveguides, provide a promising approach to overcome these drawbacks, and may lead to compact and low-cost integrated THz systems.However,up to now，there is a current lack of options for low-loss broadband transmission fibers and for functional fiber-based devices. The polymer Topas COC has both low loss and low dispersion in the THz regime and is therefore an ideal candidate for the base material of the future THz fiber/pipe.This project aims at designing, drawing, and characterizing resultant topas COC fibers /pipe for THz waveguide.The Topas COC THz fibe
