Abstract

The raising interest in Teraherz radiation (loosely defined as the 0.1–10 THz frequency range, 3000 – 30 μm wavelength range) and in the related application-oriented issues, requires the development of sensitive and performing systems exploiting powerful, stable and coherent sources as well as fast, sensitive and portable photodetectors. These key priorities prompted in the last decade a major surge of interdisciplinary research encompassing the investigation of different technologies in-between optics and microwave electronics, different physical mechanisms and a large variety of material systems offering ad-hoc properties to target the expected performance and functionalities.
