Magneto-optical effects in 2D plasmonic gratings with various types of ordering

To control light by magnetic field magneto-optical nanostructures can be used. Response of well-known periodical structures is narrowband and depending on light's incident angle. In present work we investigated magneto- optical properties of 2D periodic and quasicrystalline structures. These structures consist of gold grating-patterned layer on top of magnetic dielectric film. We showed that in 2D quasicrystalline structures magnetoplasmonic effects, such as the transverse magneto-optical Kerr effect (TMOKE) and Faraday effect, are broadband. Moreover, their independence of light's polarization and incident angle was demonstrated.
