Graphene may support electromagnetic radiation and be able to support a variety of optical devices. In general, graphene may exhibit changeability in properties such as the conductivity and the like of graphene. Graphene may comprise carbon and be of a thickness of a single atomic layer. In another embodiment, Graphene may be thicker than a single atomic layer, but may be able to exhibit changeability in the properties noted above. Disclosed herein is the guiding and manipulating of optical signals on layers of graphene to create waveguides, ribbon waveguides, beamsplitters, lenses, attenuators, mirrors, scatterers, Fourier optics, Luneburg lenses, metamaterials and other optical devices.
