Graphene nanophotonics: From fundamentals to applications

With unique possibilities for controlling light in nanoscale devices, graphene has opened new perspectives to the nanophotonics community with potential applications in metamaterials, modulators, photodetectors, and sensors. Following a brief introduction of graphene, I will address some fundamentals, such as excitation of graphene plasmon polartions [1], pushing graphene plasmons to low wavelengths, and investigating of graphene plasmon-phonon interactions [2] and light-matter interactions in graphene-metal hybrid structures [3]. Then I will discuss graphene-based optical modulators, particularly focusing on graphene-silicon platforms for electro-absorption modulating [4].
