Emission of Terahertz Radiation

2003
As described by the theory set out in Chap. 1 and proven by the experiments discussed in Chap. 4, Bloch oscillations are associated with a harmonic spatial motion of carriers. It is obvious that these carriers should thus generate radiation owing to their continuous acceleration.

A terahertz radiation spectrum analyzer

Instruments and Experimental Techniques, 2012
A spectrum analyzer of terahertz radiation pulses has been designed for spectroscopic studies of condensed media, gases, and plasmas. The operating frequency range is 0.05–6.00 THz, the frequency resolution is 0.5 cm−1, and the aperture is 40 mm.

Generation and Detection of Terahertz Radiation

2012
Methods for generating and detecting terahertz (THz) radiation are reviewed with emphasis on the physical mechanisms involved as well as the typical characteristics of the generated radiation. We first discuss methods for generating and detecting broadband pulses of THz radiation, which are based on optical femtosecond laser systems. The second section

Imaging and Sensing with Terahertz Radiation

AIP Conference Proceedings, 2005
Recent advances have revolutionized the field of terahertz imaging, and revitalized interest in the applications of this technique for imaging and non‐destructive evaluation. Here we describe the technique of terahertz time‐domain spectroscopy, and highlight some of the promising new imaging capabilities that have been demonstrated recently.

A superconducting bolometer for terahertz radiation detection

2014
In this work we present the progress on the realization of a superconducting microbolometer sensible to the THz radiation. The operation of this detector is based on an integrated antenna coupled to a suspended strip of superconducting material. The bolometer works anywhere in the temperature range 2-7 K which can be easily reached in helium bath ...
