Single-Photon Detectors in the Terahertz Range

IEEE Journal of Selected Topics in Quantum Electronics, 2011
Semiconductor quantum dot detectors as well as semiconductor charge-sensitive infrared phototransistors are described. They are the only detectors that can count single photons in the terahertz region at present. In terms of the noise equivalent power (NEP), the detectors realize experimental values on the order of 10-21 W/Hz1/2, while theoretically ...

CHIRAL METAMATERIAL ABSORBERS OF THE TERAHERTZ RANGE

Infokommunikacionnye tehnologii
The absorption effect in chiral metamaterials is associated with their unique electromagnetic properties, which are determined by the mirror asymmetry of their microstructure. These materials exhibit unusual interactions with optical waves, including controlled absorption, cross-polarization, and frequency selectivity.

The metal dielectric waveguides in the terahertz range

2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016
It is proposed that, in the terahertz wavelength range, waveguides of the class “hollow dielectric channel” be used as a guiding system. This waveguide belongs to the class of wide waveguides. A distinctive feature of this type of waveguides is their super-dimensionality, that is, the transverse dimensions of the waveguide are much longer than those of
