In this paper, we report on an approach for shaping the spectra of THz pulse generation in photoconductive antennas (PCAs) by frequency-dependent impedance modulation. We introduce a theoretical model describing PCAs, and accounting impedances photoconductor antenna. Additionally account detector response comparative analysis with experimental data. order to showcase impact modulation generation, applied simulating broadband PCAs log-spiral topology. Finally, fabricated two different...
In this Letter, optical-to-terahertz (THz) conversion of 800 nm femtosecond laser pulses in large-area bias-free InGaAs emitters based on photo-Dember (PD) and lateral (LPD) effects is experimentally investigated.

In this work, the use of electroimpedance measurements for creation respiratory frequency sensors is considered. Functional methods examination organs make it possible to detect failure well before first symptoms, as assess effectiveness therapy. research external respiration an important part clinical medicine and necessary diagnosis pulmonary diseases, evaluation treatment pathologies, obtaining up-to-date information on course Teaching patients how breathe properly persuading them lead a...
We have designed GaAs/Al 0.15 Ga 0.85 As multilayer heterostructure (MH) with diagonal transitions and optimized oscillator strength – 0.425. investigate the dependence of MH energy band profile on electric field thermal properties terahertz quantum cascade lasers (THz QCL) under different operation conditions. Furthermore, we develop a technique for fabrication THz QCL double metal waveguide via low-temperature In-Au wafer bonding followed by substrate removal. Inductively coupled plasma...
We report on InGaAs/GaAs quantum dot injection microdisk lasers laterally connected with a bus waveguide fabricated by planar technology from the same epi-structure. Various coupling schemes of microlaser are studied including attached to (zero gap), 100 nm gap for evanescence light outcoupling, and surrounding resonator. The modes outcoupling microlaser's loss (Q-factor) analyzed simulation lasers. A strong decrease in number resonance lines associated an increase resonator due is observed...
We describe a method of parameters extraction for the lumped element network representing resonant tunneling diodes (RTDs). The is based on onchip reflection coefficient measurements in wide frequency range from 1 kHz up to 60 GHz combination with differential resistance measurements. have proposed and fabricated double-barrier GaAs/AlAs RTDs embedded into 50-Ohm coplanar transmission line section, suitable RF-measurements using probe station vector analyzer. A good agreement between...
The most important regulatory function of the human body is breathing, which provided by respiratory system. In clinical practice, monitoring used to obtain information about health and make diagnoses. system can be assessed using a variety parameters, but rate. Analysis rate in patients with chronic diseases, athletes rehabilitation patients. recent years, wearable devices for continuous physiological parameters everyday life have gained momentum. Progress field portable cardiovascular has...
