Transdimensional photonic lattices with Mie-resonant nanoantennas

摘要

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