“…Figure 4c shows the influence of thickness ( H ) of the SiO 2 dielectric layer on the reflection spectra. There was an obvious redshift with the increasing thickness from 10 nm to 80 nm at the first plasmon resonance, which was opposite to the previously reported results for metal–dielectric–metal nanostructures when changing the interlayer thickness [25]. This opposite shift implies differences in the excitation mechanism between the discussed structure and the other nanostructures.…”

The miniaturization and integration of photonic devices are new requirements in the novel optics field due to the development of photonic information technology. In this paper, we report that a multifunctional layered structure of Au, SiO2 and hexagonal nanodisk film is advantageous for ultra-narrowband filtering, near-perfect absorption and sensing in a wide refractive index (RI) region. This hexagonal nanostructure presented two remarkable polarization independent plasmon resonances with near-zero reflectivity and near-perfect absorptivity under normal incidence in the visible and near-infrared spectral ranges. The narrowest full width at half maximum (FWHM) of these resonances was predicted to be excellent at 5 nm. More notably, the double plasmon resonances showed extremely obvious differences in RI responses. For the first plasmon resonance, an evident linear redshift was observed in a wide RI range from 1.00 to 1.40, and a high RI sensitivity of 600 nm/RIU was obtained compared to other plasmonic nanostructures, such as square and honeycomb-like nanostructures. For the second plasmon resonance with excellent FWHM at 946 nm, its wavelength position almost remained unmovable in the case of changing RI surrounding nanodisks in the same regime. Most unusually, its resonant wavelength was insensitive to nearly all structural parameters except the structural period. The underlying physical mechanism was analyzed in detail for double plasmon resonances. This work was significant in developing high-performance integrated optical devices for filtering, absorbing and biomedical sensing.

“…However, for the structure coated with double PCs, a factor of 16.9 at λ = 1071 nm is achieved, which is three times over that of the Au film with single PC. Comparing the small transmission enhancement in this case with only one Au nanosphere PC, it is reasonable to believe that the obtained optical transparency is with great relevant to the near-perfect optical field extraction by the plasmon modes of the other Au nanosphere PC on the rear side [26]- [28], [33]. As the Au film is sandwiched by double PCs, the excitation of the oscillation electrons [33] on both sides of the metal film is more efficient and could produce efficient light-plasmon interaction with the PCs [33].…”

Light opacity is a natural phenomenon of a continuous metal film. In various applications, such as transparent electrodes in solar cells or touching screens in ultrathin displayers, low transmittance is a major issue. Here, we present a new concept that enhances the transmission of light through a continuous metal film to reach the transmittance of glass. In order to cancel the potential electron scattering when electrons propagate in the metal film, it is sandwiched between two photonic crystal (PC) layers made of nontouching metallic particles. This geometry shows a robust, near-unity, optical transparency behavior that could be highly tuned by changing the geometrical parameters of the structure. These findings suggest potential applications in ultraintegrated optoelectronics based still benefiting from both electric and mechanical properties metals offer while still achieving optical transparency through plasmon coupling effects.

“…The study of this kind of problems also has a long tradition in the optics and physics communities. Indeed, in recent years, a lot of attention has been paid to 1-D and 2-D metallic periodic structures in connection with the huge interest raised by extraordinary transmission, metasurfaces, and related problems [18]- [23]. A good review of the combined interest of physicists and engineers on this topic can be found in [24].…”

A fully analytical multimodal equivalent circuit is presented for the modeling of the scattering of an obliquely incident plane wave by a two-dimensional (2-D) periodic array of metallic patches (or apertures in a metallic screen) embedded in a layered medium. The topology of the equivalent network is rigorously derived in the analysis and all the network parameters are given in closed form. In contrast with the previously reported explicit circuit models, the proposed approach accounts for dynamical effects over a very wide frequency range, which enables the application of the model to a great variety of situations.The key advantages of the reported multimodal network representation are its analytical nature, its extremely low-computational cost and that the physical phenomena involved in the scattering can be easily understood in terms of transmission line and lumped circuital reasonings.
