Light propagation is usually reciprocal. However, a static magnetic field along the propagation direction can break the time-reversal symmetry in the presence of magneto-optical materials. The Faraday effect in magneto-optical materials rotates the polarization plane of light, and when light travels backward the polarization is further rotated. This is applied in optical isolators, which are of crucial importance in optical systems. Faraday isolators are typically bulky due to the weak Faraday effect of available magneto-optical materials. The growing research endeavour in integrated optics demands thin-film Faraday rotators and enhancement of the Faraday effect. Here, we report significant enhancement of Faraday rotation by hybridizing plasmonics with magneto-optics. By fabricating plasmonic nanostructures on laser-deposited magneto-optical thin films, Faraday rotation is enhanced by one order of magnitude in our experiment, while high transparency is maintained. We elucidate the enhanced Faraday effect by the interplay between plasmons and different photonic waveguide modes in our system.

“…2 Several studies have been carried out to investigate the interaction between nanoparticles arranged in one-dimensional ͑1D͒ and two-dimensional ͑2D͒ arrays. [3][4][5][6][7][8][9][10][11] Previous theoretical 9,10 and experimental 4,7,11 work has focused on mode propagation in 1D chains of coupled nanoparticles with a separation much smaller than the wavelength of light, or on arrays of nanoparticles on top of metallic surfaces coupled by surface-plasmon polaritons, 6 or on arrays of metallic nanostructures coupled by guided modes in dielectric waveguides. 5 In this Rapid Communication, we provide a detailed analysis of lattice surface modes on plasmonic crystals of nanoantennas.…”

“…Using plasmons to enhance the Faraday effect has been proposed theoretically 37,38 and demonstrated experimentally. 36 The experimental demonstration suggested a hybrid plasmonic-dielectric waveguide, [39][40][41] consisting of a thin BIG film and an attached plasmonic grating, which realizes a sophisticated mechanism to enhance Faraday rotation. Here, we employ this mechanism and advance it to 220-nm-thick devices, which show five times greater polarization rotation than in previously reported experiments.…”

Tunable and switchable polarization rotation with non-reciprocal plasmonic thin films at designated wavelengths

We experimentally demonstrate an ultra-thin plasmonic optical rotator in the visible regime that induces a polarization rotation that is continuously tunable and switchable by an external magnetic field. The rotator is a magneto-plasmonic hybrid structure consisting of a magneto-optical EuSe slab and a one-dimensional plasmonic gold grating. At low temperatures, EuSe possesses a large Verdet constant and exhibits Faraday rotation, which does not saturate over a regime of several Tesla. By combining these properties with plasmonic Faraday rotation enhancement, a large tuning range of the polarization rotation of up to 8.46 for a film thickness of 220 nm is achieved. Furthermore, through experiments and simulations, we demonstrate that the unique dispersion properties of the structure enable us to tailor the wavelengths of the tunable polarization rotation to arbitrary spectral positions within the transparency window of the magneto-optical slab. The demonstrated concept might lead to important, highly integrated, non-reciprocal, photonic devices for light modulation, optical isolation, and magnetic field optical sensing. The simple fabrication of EuSe nanostructures by physical vapor deposition opens the way for many potentially interesting magneto-plasmonic systems and three-dimensional magneto-optical metamaterials.
