Graphene Magnetoplasmonics as a Platform for Creating THz and Mid-IR Devices with Combined Electrical and Magnetic Tuning

The aim of this paper is to provide an overview of the current state of graphene magnetoplasmonics, including fundamentals and applications. We consider the physical effects, including the “giant” Faraday effect, in electrically and magnetically controlled graphene magnetoplasmonic metasurfaces, as well as their use for creating new graphene-based plasmonic devices in the THz and IR range that are dynamically tunable by an external magnetic field. We present the principles of operating of electrically and magnetically tunable graphene THz and IR devices: THz absorbers, switches, polarizers, filters, sensors, modulators and integrated magneto-optical elements such as IR isolators and circulators. We discuss their applications in photonics and optoelectronics, telecommunications, THz spectrometry, and biomedical technologies.
