The bigger the interaction, the smaller and more interesting the device
Enhancing or amplifying the interactions of polarised electromagnetic radiation with magnetic materials, so-called magneto-optical (MO) effects, is a prerequisite to reducing the size of certain photonic devices and for active nanophotonic devices. Using dipolar plasmonic resonances in magnetic nanoantennas is one way to enhance MO effects. Currently, the maximum amplification possible is insufficient and intrinsically limited by the amplification process reliant on dipolar plasmons. With the support of the Marie Skłodowska-Curie Actions programme, the MANACOLIPO project is exploring a recently proposed method relying on hybrid magnetoplasmonic nanocavities to overcome this intrinsic limitation and enable an unprecedented amplification of MO effects.
