Dichroism of coupled multipolar plasmonic modes in twisted triskelion stacks
Javier RodrÃguez-Ãlvarez, Joan Vila-Comamala, Antonio GarciÃa-MartÃn +9
We present a systematic investigation of the optical response to circularly polarized illumination in twisted stacked plasmonic nanostructures. The system consissts in two identica…
Tunable circular dichroism through absorption in coupled optical modes of twisted triskelia nanostructures
Javier Rodriguez Alvarez, Antonio Garcia Martin, Arantxa Fraile Rodriguez +2
We present a system consisting of two stacked chiral plasmonic nanoelements, so-called triskelia, that exhibits a high degree of circular dichroism. The optical modes arising from…
Imaging of Antiferroelectric Dark Modes in an Inverted Plasmonic Lattice
Javier Rodriguez Alvarez, Amilcar Labarta, Juan Carlos Idrobo +8
Plasmonic lattice nanostructures are of technological interest because of their capacity to manipulate light below the diffraction limit. Here, we present a detailed study of dark…
