Recently we have shown that a nanofiber excited by a localized electric source can have enhanced electric and magnetic response depending of the relative orientation of the source and the fiber [1]. We have demonstrated that the dielectric nanofiber can suppress the electric response and enhance the magnetic response of the coupled system when excited with an electric dipole oriented along the circumference...
We report on our experimental and numerical studies of optically-induced magnetic and electric dipole resonances of spherical silicon nanoparticles. We combine polarization-resolved dark-field spectroscopy and near-field scanning optical microscopy and demonstrate experimentally that electromagnetic fields scattered by nanoparticles exhibit strong sensitivity to the probing beam polarization both...
We experimentally demonstrate spin-polarized light emission from quantum dots coupled to a single-element nanoantenna with resonant multipolar moments. We observe spin-momentum locking resulting in photons of opposite spin emitted in opposite directions.
We spectrally overlap the magnetic and electric resonances in all-dielectric silicon nanodisk arrays by tuning the disk aspect ratio. This offers new opportunities for functional metasurfaces and conceptually new all-dielectric unidirectional nanoantennas.
