The terahertz region extends from approximately 100 GHz to 10 THz and this frequency range can be considered as a link between electronics and photonics. Since the beginning of the 90s this domain was growing first with the development of time-domain spectroscopy and now is becoming more and more attractive with the emergence of new technologies: quantum cascade lasers, nano-transistors, photomixing, and mixers. Systems based on these devices have found a lot of applications exploiting unique properties of the THz domain of the electromagnetic spectrum. This conference is intended to provide a forum for scientists, engineers, and researchers from a diverse set of disciplines who are interested in either learning more about terahertz technology. The scope of the conference includes sources and detectors of THz radiation, optical components and systems for this frequency domain, as well as different applications utilizing this technology.
