太赫兹波的产生与发展

Generation and development of terahertz waves

太赫兹波位于微波和远红外之间,频率范围处在电子学和光学研究的交叉区域。近些年来,太赫兹辐射研究取得了长足进展。由于太赫兹波具有光子能量低、分辨率高、透射能力强等诸多优点,可以将其应用在医学诊断、探测、成像、通信、光谱分析等方面,目前已经成为国际上电磁辐射研究的热点。太赫兹技术发展的关键问题是产生太赫兹波的辐射源。对太赫兹波的产生与发展进行了总结,分别介绍了太赫兹波的主要性质、应用、研究现状以及产生方法,并且对太赫兹波的发展前景作了展望。

Terahertz waves are located between microwaves and far infrared,and the frequency range is at the intersection of electronics and optical research.In recent years,great progress has been made in research on terahertz radiation.Because terahertz waves have many advantages such as low photon energy,high resolution,strong transmission ability,etc.,and can be used in medical diagnosis,detection,imaging,communication,spectral analysis,etc.,and have become a hot spot in international electromagnetic radiation research.The key issue in the development of terahertz technology is the radiation source generating terahertz waves.This paper summarizes the generation and development of terahertz waves,introduces the main nature,application,research status and generation methods of terahertz waves,and prospects the development of terahertz waves.
