Abstract
We first perform numerical simulations of the near-field optical chirality around the nanostructures and show how the local chiro-optical effects around symmetric and asymmetric plasmonic and plasmonic-dielectric nanostructures can be tailored. In particular, we study simple geometries based on plasmonic nanohole arrays or nanowires or nanospheres asymmetrically covered by metal. Then, we study the influence of the nanoscale effects the overall macroscopic chiro-optical response that we can measure in various ways. We first conventionally measure extrinsic chirality by shining a widely tunable laser on the sample and measuring polarization-dependent transmission or reflection, which depends on the sample’s orientation and the incidence angle. We also study asymmetric metasurfaces by photothermal techniques: photo-acoustic and photo-deflection techniques, to measure scattering-free absorption and diffraction effects, respectively. Finally, we reveal how the plasmonic asymmetry influences the polarization states of the transmitted light (spectral and incidence angle dependence).
