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. 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 present recent results on light-matter interactions in graphene, graphene plasmon, and plasmon-phonon coupling. Finally, I will present some results on graphene for optoelectronic applications, e.g., graphene based silicon ring-resonator modulators, graphene plasmonic waveguide modulators, graphene plasmonic waveguide photodetector, and high-energy-efficiency graphene microheats.

报告人简介：Sanshui Xiao obtained his PhD degree at Zhejiang University in 2004. In August 2004, he joined the Royal Institute of Technology as a post-doc researcher. In 2006, he started to work at the Technical University of Denmark, and he is now holding Associate Professor there. His current research interests include exploration of fundamental physics of light-matter interactions at the nanoscale and development of graphene-based optoelectronic devices. He has co-organized several sessions at PIERS, AME, and EMN conferences, and obtained the European Optics Prize from the European Optical Society in 2008. He also serves the topical editor for Applied Optics.
