基于硅介质光栅的片上太赫兹波源

随着太赫兹技术的快速发展，人们对太赫兹技术在通信、光谱学和传感方面的各种应用越来越感兴趣。太赫兹技术发展与应用的基础是高性能的太赫兹源，传统的太赫兹源体积大且需要高功率电源驱动，难以适应集成太赫兹技术的发展，迫切需要研发新机制的微型太赫兹源。本文研究了一种新型微型化自由电子太赫兹辐射器，基于自由电子与其在光栅介质波导结构中激励的太赫兹波的互作用，实现太赫兹波的激励。这项研究为开发高效的片上太赫兹辐射源和拓展先进太赫兹应用提供了新的选项。

On-chip terahertz source based on silicon dielectric grating

With the rapid development of terahertz technology, people are increasingly interested in its various applications in communications, spectroscopy, and sensing. The basis for the development and application of terahertz technology is high-performance terahertz sources. Traditional terahertz sources are large in size and require high-power power supply to drive and are difficult to adapt to the development of integrated terahertz technology. Therefore, there is an urgent need to develop micro-terahertz sources with new mechanisms. This paper studies a new type of miniaturized free electron terahertz radiator, which realizes the excitation of terahertz waves based on the interaction of free electrons and the terahertz waves excited in the grating dielectric waveguide structure. This research provides new options for developing efficient on-chip terahertz radiation sources and expanding advanced terahertz applications.
