Paper Abstract

Graphene metamaterials have been theoretically demonstrated as an enabler for applications as perfect absorbers, photodetectors, directional light emitters, electro-absorption modulators, and tunable spintronic devices. We demonstrate the experimental realization of phototunable graphene metamaterials on diverse substrates by a scalable, transfer-free solution-phase deposition method. The optical properties of the metamaterials are tuned by controllable laser-mediated conversion of the graphene oxide layers into their graphene counterparts. We demonstrate the fabrication of functional photonic devices with the laser printing process, such as ultrathin flat lenses, perfect absorbers, selective photo absorber, colorful display, and devices integrated with semiconductor waveguide structures.
