Extraordinary modulation of light polarization with dark plasmons in magnetoplasmonic nanocavities

(Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, Chinese Academy) Enhancing magneto-optical effects is crucial for the size reduction of key photonic devices based on non-reciprocal propagation of light and to enable active nanophotonics. In this direction, an international team lead by CIC Nanogune (Spain) theoretically proposed and experimentally demonstrated a novel conceptual roadmap to boost magnetization-induced polarization modulation using multipolar d...
