Terahertz – Yesterday, Today, and Tomorrow
Vladimir Akimov
Momento, 2016
The term terahertz (THz) became one of the most popular words in science nowadays. Why? And what is it? Why more and more scientific books, articles, and conferences are being devoted to this topic all over the world? Why THz centers are being established at many universities and laboratories? Why do THz programs appear in different countries? The article brings you short answers to these questions. It explains what THz radiation is and what a so-called THz gap is. We touch the peculiarities of the THz radiation and mention its important applications. Then we consider the state of the art in THz science. As it is impossible to cover all the scientific and technical aspects of the THz science in the short review, therefore we only touch the semiconductor nanostructure-based devices and technologies in two most important fields; namely, we will look at THz sources and detectors, paying particular attention to their differences from conventional optical devices. And we hope that reader...

Directions in terahertz technology

Abstruct-The term 'T-rays' was coined era1 advantages over single frequency methods in the early 1990's by Bell Labs to deincluding interfering background signal eliminascribe the spectrum in the TeraHertz range tion and simultaneous acquisition of many fre-(1 THz= 10l2 Hz). The THz region of the spectrum lies on the border of where electronics and optics meet, between the mm-wave and infrared bands. Infrared sources become very dim as we approach the THz region and high speed devices struggle to reach these frequencies. Consequently, practical 0.1 THz t o 20 THz sources were difficult to obtain until recent developments in laser, quantum well and compound semiconductor technology in the 1990's. Historically, we know that each time a new band in the electromagnetic spectrum opens up, a whole new industry develops and revolves around that band.

The 2017 terahertz science and technology roadmap
Stepan Lucyszyn
Journal of Physics D: Applied Physics
Science and technologies based on terahertz frequency electromagnetic radiation (100 GHz-30 THz) have developed rapidly over the last 30 years. For most of the 20th Century, terahertz radiation, then referred to as sub-millimeter wave or far-infrared radiation, was mainly utilized by astronomers and some spectroscopists. Following the development of laser based terahertz time-domain spectroscopy in the 1980s and 1990s the field of THz science and technology expanded rapidly, to the extent that it now touches many areas from fundamental science to 'real world' applications. For example THz radiation is being used to optimize materials for new solar cells, and may also be a key technology for the next generation of airport security scanners. While the field was emerging it was possible to keep track of all new developments, however now the field has grown so much that it is increasingly difficult to follow the diverse range of new discoveries and applications that are appearing. At this point in time, when the field of THz science and technology is moving from an emerging to a more established and interdisciplinary field, it is apt to present a roadmap to help identify the breadth and future directions of the field. The aim of this roadmap is to present a snapshot of the present state of THz science and technology in 2017, and provide an opinion on the challenges and opportunities that the future holds. To be able to achieve this aim, we have invited a group of international experts to write 18 sections that cover most of the key areas of THz science and technology. We hope that The 2017 Roadmap on THz science and technology will prove to be a useful resource by providing a wide ranging introduction to the capabilities of THz radiation for those outside or just entering the field as well as providing perspective and breadth for those who are well established. We also feel that this review should serve as a useful guide for government and funding agencies.
