Paper Abstract

Planar optical elements with efficient light control at the nanoscale can be designed based on transdimensional photonic lattices that include 3D-engineered nanoantennas supporting multipole Mie resonances and arranged in the 2D arrays to harness collective effects in the nanostructure. Periodic arrays of nanoparticles have gained special attention because of extraordinary lattice resonances in proximity to the wavelength of diffraction, the so-called wavelength of Rayleigh anomaly. We show the possibility of exciting strong periodic nanoparticle resonances not only in plasmonic arrays but also in the nanoparticle lattices with the high refractive index. We perform the calculation for tungsten disulfides, which belongs to the families of van der Waals materials and transition metal dichalcogenides. Nanoparticles arrangement in a periodic array plays a crucial role resulting in collective array resonances and pronounces features in spectra.
