　　Abstract:

　　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. After having a short introduction of the Technical University of Denmark and Department of Photonic Engineering, I will firstly give a brief overview of recent activities/highlights in our group, e.g., advanced theory for investigating light-matter interactions at the nanoscale, electron spectroscopy to probe quantum plasmonics, and plasmonics laser color printing. Then, I will mainly discuss how to push graphene plasmons to the near-infrared region and how to explore graphene for optoelectronic applications. I will present our recent results on graphene based silicon ring-resonator modulators, graphene plasmonic waveguide modulators, and high-energy-efficiency graphene microheats with the aid of slow-light effect arisen from the photonic crystal waveguide.
