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 non-magnetic hyperbolic nanoparticles. We demonstrate that the magneto-optical response is driven by fundamental electric and magnetic dipole modes induced by the hyperbolic dispersion. Magnetic circular dichroism experiments confirm the theoretical predictions and reveal tunable magneto-optical activity across the visible and near infrared spectral range. [less ▲]

Optical platforms enabling the dynamic real-time control of the fundamental properties of light at visible and near-infrared wavelengths are the essential components for the future optical devices. Combining magnetic materials with the metallic and all-dielectric nano-optics enables a simultaneous enhancement and mutual control of their magneto-optical and chiro-optical properties. Here we examine hybrid nanoantennas made of Si and ferromagnetic metal developing magnetically-controlled chiroptical surfaces. [less ▲]
