Abstract

We analyze the absorption of a graphene nanoribbon placed into an optical cavity. We demonstrate the existence of strong coupling between the Van-Hove singularities in armchair graphene nanoribbons and the modes of optical cavity, and calculate the dispersion of the resulting hybrid eigenmodes of the structure. We demonstrate that the total absorption of the structure can be enhanced dramatically being tuned via the Fano resonance.
