Magnetoplasmonic nanocavities for the amplification of magneto-optical activity via hybridization with dark plasmons

• Magneto-optical (MO) effects are widely used in studying magnetic materials as well as to realize optical devices exploiting non-reciprocal propagation of light. Enhancing MO effects is crucial for size reduction of key photonic devices based on non-reciprocal propagation of light and to enable active nanophotonics. Here, we disclose a promising approach that exploits multipolar Fano resonances excitable in symmetry broken magnetoplasmonic nanocavities and arising from the hybridization of dark plasmons with dipolar plasmonic resonances to induce a large amplification of magneto-optical activity.
