The study shows that active nanophotonics can be achieved by controlling the optical anisotropy on the magneto-optical activity in nonmagnetic hyperbolic nanoparticles, leading to tunable magneto-optical activity across the visible and near infrared spectral range. This is driven by the coupling of metallic-induced electric and dielectric-induced magnetic dipolar optical modes with static magnetic fields.
Active nanophotonics can be realized by controlling the optical properties of materials with external magnetic fields. Here, we explore the influence of optical anisotropy on the magneto-optical activity in nonmagnetic hyperbolic nanoparticles. We demonstrate that the magneto-optical response is driven by the hyperbolic dispersion via the coupling of metallic-induced electric and dielectric-induced magnetic dipolar optical modes with static magnetic fields. Magnetic circular dichroism experiments confirm the theoretical predictions and reveal tunable magneto-optical activity across the visible and near infrared spectral range.
