Modern nanotechnologies allow producing a variety of core-shell nanoparticles from various metals and materials, with different sizes, shapes and combinations of materials, possessing unique optical properties when immersed in liquid, solid or gaseous media. Among them, it is worth noting nanoparticles with the core-shell structure SiO<sub>2</sub>-Au, Au-SiO<sub>2</sub>, Au-Ag, Ti-TiO<sub>2</sub>, Ni-NiO, NiO-Ni, Cu<sub>2</sub>O-Au, Fe<sub>3</sub>O<sub>4</sub>-Au and others, the properties and areas of applications of which were analyzed. The results of studying the optical properties of various core-shell nanoparticles in a wide range of wavelengths and their parameters are presented and analyzed. The use of nanoparticles selected on the basis of the presented analysis of absorption, scattering and attenuation of optical and solar radiation can be used to develop and implement various devices that provide unique advantages over traditional devices in the control and use of optical radiation. These results can be used to design and apply optical absorbers, scatterers, filters, attenuators and other devices based on them to control and modify radiation properties, especially for high-temperature nanophotonics applications. They can play a decisive role in improving the efficiency of solar and optical energy applications.

We replaced the material with a metamaterial, focused on its characteristic magnetic response, and studied its interaction with the magnetic field inside a Fabry-Pérot (FP) microcavity. In this study, we utilized the fact that a rectangular hole metamaterial (RH), known as a magnetic current antenna, behaves as a magnetic dipole. This RH also has a high reflectance, so it also functions as a mirror. Taking advantage of this property, we investigated the optical properties of three different FP cavity structures containing RH metamaterials in the THz region. First, we investigated the transmission properties and dispersion relationship by transmission line theory analysis. Next, to fabricate the actual sample, we designed it using the finite differential time domain (FDTD) method and investigated the magnetic field distribution inside the sample. We then fabricated a sample by photolithography and lift-off processes and measured its transmission spectra using THz time-domain spectroscopy. As a result, we found that it was possible to observe triple-coupled normal mode splitting caused by the strong coupling between the magnetic field and the magnetic dipole. This phenomenon does not appear in a strongly coupled system of two coupled oscillators, such as the well-known cavity polariton, which consists of an ordinary electric field and an electric dipole.</div></div>","PeriodicalId":49699,"journal":{"name":"Photonics and Nanostructures-Fundamentals and Applications","volume":"62 ","pages":"Article 101313"},"PeriodicalIF":2.5,"publicationDate":"2024-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142326845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed sensor, operating with varying refractive indices in the background cladding, demonstrates a sensitivity of 218 nm/RIU and a total quality factor of 1198. A comprehensive analysis of the bending loss in the proposed sensor is conducted, elucidating its impact on sensitivity, coupling quality factor, and intrinsic quality factor. This analysis aids in the selection of optimal ring resonator parameters, including radius, width, and gap, to achieve superior sensing performance. Furthermore, the paper examines the effect of dispersion on sensitivity and quality and compares the results with those obtained from CMT-based silicon core ring resonator and disk resonator RI sensors.
