Advantages of optical modulation in terahertz imaging for study of graphene layers
Rusnė Ivaškevičiūtė-Povilauskienė, Alesia Paddubskaya, Dalius Seliuta +7
It was demonstrated that optical modulation together with simultaneous terahertz (THz) imaging application enables an increase in contrast by an order of magnitude illustrating hen…
Observation of the Dissipative Parametric Gain in a GaAs/AlGaAs Superlattice
Vladislovas Čižas, Liudvikas Subačius, Natalia V. Alexeeva +5
Parametric generation of oscillations and waves is a paradigm, which is known to be realized in various physical systems. Unique properties of quantum superlattices allow to invest…
Field Effect Transistors for Terahertz Detection: Physics and First Imaging Applications
W. Knap, M. Dyakonov, D. Coquillat +11
Resonant frequencies of the two-dimensional plasma in FETs increase with the reduction of the channel dimensions and can reach the THz range for sub-micron gate lengths. Nonlinear…
Terahertz sensing by beryllium and silicon delta-doped GaAs/AlAs quantum wells
D. Seliuta, J. Kavaliauskas, B. Cechavicius +8
Selective sensing of terahertz (THz) radiation by beryllium and silicon delta-doped GaAs/AlAs multiple quantum wells (MQWs) is demonstrated. A sensitivity up to 0.3 V/W within 0.5{…
Terahertz detection with delta-doped GaAs/AlAs multiple quantum wells
D. Seliuta, B. Cechavicius, J. Kavaliauskas +10
The authors demonstrate selective detection of terahertz radiation employing beryllium delta-doped GaAs/AlAs multiple quantum wells. The sensitivity up to 1 V/W within 4.2-7.3 THz…
