Optical Transistor for an Amplification of Radiation in a Broadband THz Domain [PDF]
, 2020 We propose a new type of optical transistor for a broadband amplification of THz radiation. It is made of a graphene--superconductor hybrid, where electrons and Cooper pairs couple by Coulomb forces. The transistor operates via the propagation of surface

Strong Terahertz Radiation from a Liquid-Water Line [PDF]
Physical Review Applied, 2018 Terahertz radiation generation from liquid water has long been considered impossible due to strong absorption. A few very recent works reported terahertz generation from water, but the mechanism is not clear and the efficiency demands to be enhanced.

Phase-Insensitive Scattering of Terahertz Radiation [PDF]
Photonics, 2017 The nonlinear interaction between Near-Infrared (NIR) and Terahertz pulses is principally investigated as a means for the detection of radiation in the hardly accessible THz spectral region. Most studies have targeted second-order nonlinear processes, given their higher efficiencies, and only a limited number have addressed third-order nonlinear ...

Magnetic field effect on tunnel ionization of deep impurities by terahertz radiation [PDF]
, 2003 A suppression of tunnelling ionization of deep impurities in terahertz frequency electric fields by a magnetic field is observed. It is shown that the ionization probability at external magnetic field, B, oriented perpendicular to the electric field of ...
