“…As a rule of thumb, resonant properties of regular 1D [21,22] or 2D [23] arrays are significantly suppressed in the presence of the substrate. Though, in the stratified medium, the existence of different coupling scenarios between plasmonic and photonic modes can be exploited in sensors [24], nanoantennas [25], and other applications [26][27][28].…”

We analytically and numerically study coupling mechanisms between 1D photonic crystal (PhC) and 2D array of plasmonic nanoparticles (NPs) embedded in its defect layer. We introduce general formalism to explain and predict the emergence of PhC-mediated Wood-Rayleigh anomalies, which spectral positions agree well with the results of exact simulations with Finite-Difference Time-Domain (FDTD) method. Electromagnetic coupling between localized surface plasmon resonance (LSPR) and PhC-mediated Wood-Rayleigh anomalies makes it possible to efficiently tailor PhC modes. The understanding of coupling mechanisms in such hybrid system paves a way for optimal design of sensors, light absorbers, modulators and other types of modern photonic devices with controllable optical properties.

“…To add magnetic functionality and, at the same time, keep optical losses at a moderate level, one could introduce magnetic dielectric materials surrounding noble metal particles. Considering this option, one of the most optimal configurations for magnetoplasmonic nanoantennas is represented by noble metal nanoparticles conjugated to a bulk magnetic insulator such as Bi‐substituted iron garnet . For this functional material, it has been demonstrated that LSPRs can enhance the magneto‐optical Faraday effect by about 20 times.…”

In the past decade, the investigation of plasmonic and magnetoplasmonic nanostructures and, in particular, nanoantennas has attracted significant research interest. [1][2][3][4][5][6] The attention is largely driven by the prospect to control light at subwavelength scales and the necessity of coupling optical and electrical devices. Magnetic properties of such nanostructures are of importance due to nonreciprocal light propagation [7][8][9][10][11][12] and the feasibility of the control of the polarization and intensity of light in a broad spectral range.

Light localization by metal particles of nanometer size allows to not only control the propagation of light, but also enhance magneto‐optical effects. The influence of the immersion of gold nanodisks inside a transparent magnetic medium, namely, Bi‐substituted iron garnet, is investigated, and the optimal position of the nanoparticles within the magnetic material for a strong enhancement of the effect is unraveled. Three samples with periodic arrays of Au cylinders are studied: disks on the surface of the magnetic dielectric film, inside the magnetic film, and directly under the magnetic film. The largest enhancement of the Faraday effect mediated by a localized surface plasmon resonance takes place when nanodisks are submerged inside the magnetic film at a few nanometers below its upper surface. It is shown that the most prominent influence on the Faraday effect enhancement is provided by the magnetic medium between the nanodisks. The experimental results are in good agreement with the numerical analysis.
