ABSTRACT

Abstract Anisotropic borophene surface plasmons with extraordinary features have triggered considerable research interest since its discovery. However, due to the atomically thin thickness of monolayer borophene, it is difficult to achieve borophene surface plasmons with high absorption, especially for high-order plasmonic resonant modes. In this paper, we theoretically proposed a hybrid plasmonic system consisting of a borophene monolayer and a periodic metallic grating separated by a dielectric spacer, where multi-order anisotropic borophene surface plasmons and magnetic polaritons can be simultaneously excited. Benefitting from the high electric field enhancement and localization of the magnetic polaritons, the intrinsic absorption of the multi-order borophene surface plasmons can be improved by at least 3 times when the resonant wavelengths of borophene plasmons and magnetic polaritons are tailored to match each other, either by passively tuning the height of grating slits or by actively adjusting the borophene electron density. By further designing compound grating with multiple slits in one period, the overall absorption of the system can be significantly improved within a wide infrared region. Such hybrid system with may find applications in the design of boron-based optoelectronics devices in the infrared region.
