Absorption in the long-wave infrared band is an important focus of infrared research and has attracted a great deal of attention from researchers. In this work, a long-wave infrared ultra-wideband absorber based on a four-layer metal–dielectric–metal–dielectric structure is proposed. In the ultra-long operating band of 8–36 μm, the average absorption rate is as high as 95.79 %, brought about by the resonance excitation of various modes, including local surface plasmon resonance, guided mode resonance, cavity resonance, magnetic resonance, and diffraction. At a large incidence angle of 60°, the absorption of the absorber can reach 91.17 % in TE mode, demonstrating insensitivity to large-angle incidence. At 1800 K, the absorber shows an emission efficiency as high as 97.01 % in the long-wave infrared range. It is worth mentioning that our absorber exhibits an extremely large manufacturing tolerance of ± 0.4 μm, making it highly suitable for practical production and application. Therefore, the proposed absorber shows promising potential in applications such as infrared imaging, infrared detection, hot electron collection, radiative cooling, and other related fields. In addition, the absorber can be used in remote sensing applications, as its operating band effectively covers the common remote sensing band from 8 to 30 μm.</div></div>","PeriodicalId":49699,"journal":{"name":"Photonics and Nanostructures-Fundamentals and Applications","volume":"63 ","pages":"Article 101357"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143168032","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}

By regulating the Fermi energy of the Dirac semimetals, it becomes possible to adjust the frequency of the absorption peaks of the absorber. Specifically, when a Fermi energy of 50 meV was chosen for the Dirac semimetal, four absorption peaks were generated within the 4–8 THz range, and all of these peaks boasted absorption rates exceeding 95 %. Firstly, the structural characteristics of the absorber were introduced, and its feasibility was demonstrated by relying on the impedance matching theory. Subsequently, the variations in the electric field on the surface of the absorber were investigated through the application of the Local Surface Plasmon Resonance (LSPR) theory. Moreover, by modifying the structural parameters, it was found that the absorber possesses excellent physical tuning capabilities. After exploring how changes in the environmental refractive index influence the device's functionality, it was also discovered that the absorber shows remarkable sensitivity to the refractive index, reaching 1840 GHz/RIU. This makes it a highly promising candidate for sensing applications.

This paper reports that PVBs at telecommunication wavelengths can be generated through phase modulation in a single dielectric metasurface. The metasurface enables to generate PVBs with two distinct topological charges under orthogonal circular polarization illumination by employing a spin-multiplexing design strategy. Numerical simulations demonstrate that the radius of a PVB can be manipulated by modifying the structural parameters of the designed metasurface with high design flexibility. Further modulation of the polarization state of the incident light allows for the linear superposition of two PVBs with orthogonal circular polarization states to create a perfect Poincaré beam (PPB), which is characterized by a vectorial optical field on a higher-order Poincaré sphere.
