Abstract
Graphene is an atom-thick material that shows distinct electrical and mechanical properties, thanks to its hexagonal-lattice of carbon atoms. For instance, graphene-based-platforms offer a basis for compact and tunable photonic devices. This is because graphene waveguides offer nanoscale optical confinement, tunable graphene conductivity in the optical range, desirable properties of being able to stand alone, and good compatibility with a wide diversity of optical and electronic materials. In this presentation, we present our recent work on exploiting graphene layers to achieve frequency switching, and giant amplification, of photonic signals in the terahertz frequency range, owing to the distinct graphene
properties.
