We report the observation of the electro-optic effect in Bi Se crystals induced by an intense single-cycle terahertz pulse. The effect reveals itself as a transient change of the polarization state of a femtosecond laser pulse reflected from the crystal that is exposed to the terahertz electric field. The corresponding experimental signal follows the field with a ...

One of the principal specifics of future 6G systems operating in the subterahertz and terahertz frequency bands (0.1–0.3 THz and 0.3–3 THz) is that a part of the base station (BS) coverage will be located in the near-field region. As in this region, the signal received power (SRP) heavily depends not only on the separation ...

The quality of wireless connections in the sixth-generation (6G) communication networks is tightly linked to the capabilities of smart antenna environments. They should enable effective routing of ultra-narrow radio beams, intrinsic to D-band channels, and make use of so-called reconfigurable intelligent surfaces (RISs). Practical RISs are seriously judged by their cost and operation efficiencies. In ...

In this paper, computer modelling of the main parameters of an antenna with topology based on Koch fractal and meta-surface is performed. The simulation results of such an antenna on a 65 x 65 x 1.5 mm PCB with one and two layers of metamaterial are obtained. The influence of the metamaterial and its distance ...

Comprehensive studies of the luminescence of p–i–n structures with 10 compensated GaAs/AlGaAs quantum wells have been performed. The studies were carried out in the terahertz (THz) and near-infrared (NIR) spectral ranges with both optical and electrical pumping of nonequilibrium charge carriers. The THz photoluminescence spectra revealed an emission line caused by electron transitions from the first size-quantization ...

The interaction of a single-cycle terahertz electric field with the topological insulator MnBi2Te4 triggers strongly anharmonic lattice dynamics, promoting fully coherent energy transfer between the otherwise noninteracting Raman-active Eg and infrared (IR)-active Eu phononic modes. Two-dimensional terahertz spectroscopy combined with modeling based on the classical equations of motion and symmetry analysis reveals the multistage process underlying the excitation of the ...

Terahertz (THz) luminescence in doped nanostructures with GaAs/AlGaAs quantum wells is studied under conditions of interband optical pumping. The study is carried out on compensated quantum wells with different doping profiles. In one structure, compensation is carried out directly in each quantum well by introducing donors and acceptors with the same concentration. In the other, ...

We study photoluminescence of InP/InAsP/InP nanostructures monolithically integrated
to a Si(100) substrate. The InP/InAsP/InP nanostructures were grown in pre-formed pits in the
silicon substrate using an original approach based on selective area growth and driven by a molten
alloy in metal–organic vapor epitaxy method. This approach provides the selective-area synthesis of
the ordered emitters arrays on Si substrates. The ...

Here, we report on our recent efforts to develop of a photodetector based on single-layer graphene two-terminal device on the sapphire substrate. Our detector operates at 1.55μm, which corresponds to the telecom window. We have demonstrated that our detector operates under zero bias conditions at room temperature, and the signal-to-noise ratio reaches 45dB. The measured frequency ...
