Magnetoplasmonic Dipole Nanoantenna for Reconfigurable Optical Communications

We show that magneto-optical (MO) effects in magnetoplasmonic dipole nanoantennas, built by plasmonic ferromagnetic materials, enable active beam steering of the radiated fields. Our design, working at the visible wavelength λ=690nm, is promising for applications in intra- and inter-chip reconfigurable optical nanolinks for future 6G communication networks.
