    太赫兹波是指频率在0.3-10太赫兹(波长从1mm到30μm)范围内的电磁波,介于微波和红外辐射之间。自20世纪80年代后期太赫兹时域光谱技术首次被开发以来, 太赫兹波逐渐受到科学界的关注。进入21世纪后,更是在世界范围内引发了一个研究太赫兹波的高潮,尤其在近几年取得了令人瞩目的科研成果。随着太赫兹波段高效率发射源和灵敏探测器的出现,使得我们对太赫兹波基础科学理论的认识和理解有了新的依据。

    在早期,太赫兹技术主要用来研究天文学领域中宇宙背景的远红外辐射和激光核聚变领域中的等离子体诊断。然而随着研究的不断深入,太赫兹科学与技术在诸多领域表现出了极大的应用潜力,例如在太赫兹波与物质相互作用、太赫兹波光谱与成像、太赫兹波无损探伤、太赫兹波安全检测、太赫兹波生物医学等方面。可以预见,太赫兹技术在成像和其它交叉学科领域的转型发展将是21世纪最具前途的研究之一。

    与之相对的在电磁波谱中位于太赫兹波两侧的微波和红外辐射早已被广泛地应用在通信、探测、光谱、成像等众多领域,而太赫兹波段的电磁辐射并没有得到深入的研究,也只有及少量的技术和屈指可数的应用,成为电磁波谱中一段不为人熟悉的“空白”,即太赫兹间隙(THz gap)。科技在不断进步,得益于超快光子学技术和低尺寸半导体技术的发展,为太赫兹波段提供了合适的辐射源和探测手段,太赫兹科学与技术才得以飞速地发展。

    受《光电子前沿》编辑部之托,我编写了“太赫兹科学、技术与应用专刊”,该专刊为第一期,主要收录了5篇评论性和研究性的文章,分别由我之前在伦斯勒理工学院太赫兹研究中心才华横溢的5位毕业生贡献,他们分别是Yuting W. Chen博士、Jingle Liu博士、 Xiaofei Lu博士、I-Chen Ho博士和Benjamin Clough博士。此专刊包括5个前沿研究领域:太赫兹防反射硅结构(Dr.Chen)、太赫兹遥感探测(Dr.Liu)、太赫兹空气光子学(Dr.Lu)、非线性太赫兹波与物质相互作用(Dr.Ho)以及太赫兹增强声学(Dr.Clough),并且希望该专刊能够为研究太赫兹波的研究人员提供帮助,起到抛砖引玉的作用。

    在此,我要感谢许多同事和朋友的指导和支持,尤其感谢Dr. David Auston, Dr. Chi Lee, Dr. Dan Grischkowsky, Dr. Dan Mittleman, Dr. Peter Siegel, Dr. Qing Hu, Dr. Keith Nelson, Dr.Charles Schmuttenmaer, Dr. Peter Jepsen, Dr. Paul Planken, Dr. Kiyomi Sakai, Dr. Cunlin Zhang, Dr. Jianquan Yao, Dr. Jinsong Liu, Dr. Gun-Sik Park, and Dr. Alexander Shkurinov。

    同时,我也要感谢之前从伦斯勒理工学院太赫兹研究团队毕业的所有学生: Ms. Yahong Jin, Ph.D, 1994; Mr. Xinfa Ma, Ph.D, 1995; Mr. Greg Wagoner, Ph.D, 1997; Mr. Qi Wu, Ph.D, 1997; Ms. Jennifer Riordan, Ph.D, 1998; Mr. Ming Li, Ph.D, 2000; Mr. Pengyu Han, Ph.D, 2000; Mr. F.

Preface

I am delighted to introduce the first special issue on THz wave science, technology, and application. This issue contains five review and research papers, all written by former PhD students, Dr. Yuting Chen, Dr. Jingle Liu, Dr. Xiaofei Lu, Dr. Karen Ho, and Dr. Ben Clough, at the Center of THz Research, Rensselaer Polytechnic Institute. These gifted scientists and engineers are the most brilliant and dedicated students graduated in the THz community in the past four years. This issue covers research frontiers from THz antireflection silicon structure (Dr. Chen), THz wave remote sensing (Dr. Liu), THz wave air photonics (Dr. Lu), nonlinear THz wave-matter interaction (Dr. Ho), and THz enhanced acoustics (Dr. Clough). 
 
Terahertz (THz) radiation, which is electromagnetic radiation in a frequency interval from 0.3 to 10 THz (1 mm – 30 μm wavelength), is the next frontier in science and technology. This band occupies a large portion of the electromagnetic spectrum between the infrared and microwave bands. Basic research, new initiatives, and developments in advanced sensing and imaging technology, with regards to the THz band, remain unexplored compared with the relatively well-developed science and technology in the microwave and optical frequencies.
 
Historically, THz technologies were used mainly within the astronomy community for studying the background of cosmic far-infrared radiation, and by the laser-fusion community for the diagnostics of plasmas. Since the first demonstration of THz wave time-domain spectroscopy in the late 1980’s, there have been a series of significant advances (particularly in recent years). More intense THz sources and higher sensitivity detectors are providing new opportunities for understanding the basic science in the THz frequency range. 
 
As developments move forward, THz science will not only have an impact on material characterization and identification. It will also have potential applications in the fields of communications, imaging, medical diagnosis, health monitoring, environmental control, and chemical and biological sensing, as well as security and quality control applications. Twenty-first century research in the THz band is one of the most promising areas of study for transformational advances in imaging and other interdisciplinary fields.
 
The THz frequency range is the last segment of the electromagnetic spectrum to be conquered. Far from being fully explored, it offers great opportunities in science, innovation, new technology and applied fields.
 
I thank many colleagues and friends for their guidance, support, and friendship. Special thanks to Dr. David Auston, Dr. Chi Lee, Dr. Dan Grischkowsky, Dr. Dan Mittleman, Dr. Peter Siegel, Dr. Qing Hu, Dr. Keith Nelson, Dr. Charles Schmuttenmaer, Dr. Peter Jepsen, Dr. Paul Planken, Dr. Kiyomi Sakai, Dr. Cunlin Zhang, Dr. Jianquan Yao, Dr. Jinsong Liu, Dr. Gun-Sik Park, and Dr. Alexander Shkurinov.

Selected materials used in this issue come from Dr. Jingle Liu, Dr. I-Chen Ho, Dr. Xiaofei Lu, Dr. Yuting Chen, and Dr. Benjamin Clough’s research.
 
I also thank our senior researchers (postdoctoral associates, research associates, research assistant professors, and visiting scholars): Dr. Wang Li, Dr. Zhiping Jiang, Dr. Gyu Cheon Cho, Dr. Masahiko Tani, Dr. Bradley Ferguson, Dr. Samuel Mickan, Dr. Xuguang Huang, Dr. Yuchuang Chen, Dr. Jiayin Qin, Dr. Abdellah Menikh, Dr. Zhengguo Lu, Dr. Yunqing Chen, Dr. Albert Redo, Dr. Jianming Dai, Dr. Jin Wook Choi, Dr. Abul Azad, Dr. Ying Hu, Dr. Wei Liang, Dr. Yuguang Zhao, Dr. Cunlin Zhang, Dr. Guozhong Zhao, Dr. Yan Zhang, Dr. Hongwei Zhao, Dr. Hongkyu Park, and Dr. Etienne Gagnon, Dr. George Gehring, Dr. Bianca Jackson, Dr. Liangliang Zhang, Dr. Yan Peng, and Dr. Ilya Vugmeyster. They are key players in our group, and have dedicated their time and effort to advancing THz research.
 
This special issue is for my former student heroine, Dr. Hua Zhong. She earned a BS from Peking University, and received a PhD in Physics at Rensselaer Polytechnic Institute in 2006. She made an impact in the development of THz science and technology. She was the first one, together with her classmate Dr. Xu Xie, to use THz waves for defect detection in thermal insulating foams for the NASA’s space shuttle program.  She was the first researcher to report the THz wave emission pattern from laser induced air plasma with two-color laser excitation, which was important to develop intense broadband THz source with laser pulses. Dr. Hua Zhong returned to China to serve her motherland right after graduation. Unfortunately, she was diagnosed with cancer when she served as a volunteer for the Beijing Olympic Games. After fighting cancer for five years, Dr. Hua Zhong left us in Dec. 8, 2013. I will always remember her smiling face, soft voice, creative paintings, and her love. She passed away at age of 35, I am writing this paragraph with tears. This issue celebrates Dr. Hua Zhong’s young life. She is forever my heroine.
