Perfect ultraviolet absorption in graphene using the magnetic resonance of an all-dielectric nanostructure
Abstract:
The enhancement of light-matter interaction for monolayer graphene is of great importance on many photonic and optoelectronic applications. With the aim of perfect ultraviolet trapping on monolayer graphene, we adopt the design of an all-dielectric nanostructure, in which the magnetic resonance of optical field is combined with an ultraviolet mirror. The physics inside is revealed in comparison with the conventional plasmonic perfect absorber, and various influence factors of absorption bands are systematically investigated. In the ultraviolet range, an optimized absorbance ratio up to 99.7% is reached, which is 10 times more than that of the suspended graphene, and the absorption bands are linearly reconfigurable by angular manipulation of incident light. The scheme for perfect ultraviolet trapping in a sub-nanometer scale paves the way for developing more promising ultraviolet devices based on graphene and potentially other 2D materials.
