Optical frequency combs (OFCs), which establish a rigid phase-coherent link between the microwave and optical domains of electromagnetic spectrum, are emerging as key high-precision tools for development quantum technology platforms. These include potential applications communication, computation, information, sensing, metrology can extend from near-infrared with micro-resonator combs, up to technologically attractive terahertz (THz) range, powerful miniaturized cascade laser (QCL) FCs. The...
Evaluation of contaminated sites is usually performed by chemical analysis pollutants in soil. This not enough either to evaluate the environmental risk soil nor efficiency cleanup techniques. Information on bioavailability complex mixtures xenobiotics and degradation products cannot be totally provided analytical data, but results from bioassays can integrate effects mixtures. In preservation human health environment quality, it important assess ecotoxicological soils obtain a better...
Abstract Titanium disulfide is a quasi‐2D transition‐metal dichalcogenide relevant for various potential applications. To exploit its technological capabilities, it important to determine fundamental properties including the lattice dynamics. The TiS 2 phonon dispersion curves available date do not reproduce properly experimental data several reasons: i) all are taken into consideration, thus poor theory‐experiment agreements have been obtained; ii) (unknown) frequency of infrared mode A 2u...
Optical frequency comb synthesizers, operating in the harmonic regime, are metrological sources which emitted optical power is concentrated a few modes, spaced by several multiples of cavity free spectral range (FSR). This behavior reflects large correlation degree and, principle, an increased per mode. In miniaturized quantum cascade lasers (QCLs), combs (HFCs) hence particularly attracting to explore effects between adjacent enabled inherently gain media third-order
Abstract Optical resonators are fundamental building blocks of photonic systems, enabling meta-surfaces, sensors, and transmission filters to be developed for a range applications. Sub-wavelength size (< λ/10) resonators, including planar split-ring at the forefront research owing their potential light manipulation, sensing applications exploring light-matter coupling phenomena. Near-field microscopy has emerged as valuable tool mode imaging in sub-wavelength terahertz (THz) frequency...
The so-called terahertz band of the electromagnetic spectrum falls in a spectral region where traditional electronic technologies fail to operate owing extremely short switching times required. In this paper, we demonstrate design three optical logic gates fabricated by three-dimensional printing, which can perform OR, AND, and XOR operations at 130 GHz. order optimize our designs used finite element simulation. amplitude spectra experimental measurements devices are presented good agreement...
Terahertz attenuated total reflectance (THz-ATR) is being extensively used for spectroscopy and imaging applications in materials science, chemistry, biomedical research. One of the driving motivations its potential studying protein dynamics, identifying living tissues, or detecting herbicide traces, as a nondestructive nonionizing technique. It well known that biological chemical samples terahertz range represents real challenge because presence water, which highly absorbing. In this work,...
This research addresses the complex issues encountered when studying biological and chemical samples in terahertz (THz) range, mainly due to water's high absorption properties. Using THz-Attenuated Total Reflectance (ATR) spectroscopy, we investigate water NaCl solutions provide both experimental data a comprehensive interpretation of optical phenomena observed. . Our focus lies understanding changes ATR responses THz range for bulk thin film forms, using non-linear regression analysis...
