摘要
太赫兹技术在下一代通信、生物成像、质量监测等领域应用潜力巨大,高品质太赫兹波导的研制使轻量化、小型化太赫兹系统成为可能,是推动太赫兹技术发展的关键。本文根据不同基材,将太赫兹波导分为金属波导、聚合物波导及复合波导,对其发展情况进行梳理,并对太赫兹聚合物波导这种高柔性、低成本导波技术进行重点介绍,讨论其不同的导光机制;最后对太赫兹导波技术进行了总结,并针对制约太赫兹波导商品化推广应用的瓶颈问题进行了初步探讨。
Terahertz(THz)technology has great potential in the next generation communication,biological imaging,quality monitoring and other fields,and the development of high-quality terahertz waveguides makes it possible to creat lightweight and miniaturized terahertz systems,which is vital to promote the development of terahertz technology.In this paper,terahertz waveguides are divided into metal waveguides,polymer waveguides and composite waveguides according to different materials.Terahertz polymer waveguides with high flexibility and low cost are emphatically introduced,and different guiding mechanisms are discussed.Finally,the technology of guiding terahertz wave is summarized,and the bottleneck problem restricting the commercial application of terahertz waveguide is preliminarily discussed.
