Abstract

We discuss the unique possibilities of graphene-based THz metasurfaces and we present the experimental and theoretical study of an ultrafast graphene-based thin film absorption modulator for operation in the THz regime. The stimulus is a near-IR pulse that generates hot carriers in the graphene metasurface reducing its conductivity.
