“…The MO all-dielectric metasurfaces offer an alternative route to solve these problems. − Several recent works have reported the enhancements of the MO effects by the Mie resonance or waveguide mode-induced field localization in the all-dielectric MO metasurfaces. − Compared to the plasmonic structures, the all-dielectric MO metasurfaces made of high-index materials avoid the issues of absorption losses. ,,− High refractive index (HRI) dielectric nanostructures can show not only electric but also strong magnetic mode resonances . These unique optical resonances, their multimodal interference, the strong localization of electromagnetic field, and very low losses make HRI dielectric nanostructures become a powerful alternative to plasmonic structures. , This approach is possible to enhance both the Faraday effect and FOM simultaneously, which is important for sensing and magnetometry applications. − In particular, the Faraday effect and the FOM are proposed to be simultaneously enhanced in MO metasurfaces, which is very promising for device applications.…”

Enhancement of the Faraday Effect and Magneto-optical Figure of Merit in All-Dielectric Metasurfaces

All-dielectric metasurfaces are promising candidates for the next-generation planar photonic devices. Magneto-optical (MO) all-dielectric metasurfaces are particularly attractive due to their enhanced MO response at the subwavelength scale. In this paper, we report a MO all-dielectric metasurface based on a Ce:YIG thin film and a two-dimensional array of the silicon nanoresonators. Compared to a bare Ce:YIG film, the device shows a four times enhancement of the Faraday effect and the MO figure of merit (FOM) at 1370 nm wavelength. The high Faraday rotation (FR) and FOM are caused by the increase in the interaction time between light and magnetic matter which is indicated by the local field increase inside the Ce:YIG film when exciting the hybrid Mie resonance-waveguide modes. Simultaneously enhanced FR and FOM make the dielectric MO metasurfaces promising candidates for free-space MO devices such as MO sensors, MO modulators, and nonreciprocal photonic devices.

“…The experimental results demonstrate the effectiveness of the hyperbolic waveguide in the microwave regime, and this design can be easily extended to a higher frequency range using a natural 2D hyperbolic medium or hyperbolic metasurfaces. [ 86,87 ] Therefore, the results not only reveal the sophisticated electromagnetic functionalities of hyperbolic waveguides in the near field but also may provide opportunities for developing integrated optical devices, such as splitters, directional radiation antennas, and planar miniaturized couplers.…”

Planar waveguides limit the transmission of electromagnetic waves in a specific direction and have a wide range of applications in filters, sensors, and energy‐transfer devices. However, given the increasing demand for planar‐integrated photonics, new waveguides are required with excellent characteristics such as more functionality, greater efficiency, and smaller size. Herein, the experimental results for a planar microwave‐regime waveguide fabricated from circuit‐based magnetic hyperbolic metamaterial (HMM) are reported. HMM is a special type of anisotropic metamaterial, whose isofrequency contour (IFC) takes the form of an open hyperboloid. Because of the open‐dispersion IFCs, HMMs support propagating high‐k modes with large effective refractive indices, which allow planar hyperbolic waveguides to be miniaturized. Especially, as opposed to the traditional dielectric slab waveguide, the group velocity and phase velocity in hyperbolic waveguides are oriented in opposite directions—a characteristic that is exploited to realize the backward propagation of electromagnetic waves. Based on this property, a backward coupler based on the hyperbolic waveguide is designed and experimented with. Herein, the significant potential of circuit‐based platforms for the experimental study of the propagation and coupling of guided modes is not only revealed but also the use of HMMs for numerous integrated functional devices is promoted.
