报告摘要：With unique possibilities for controlling light in nanoscale devices, two-dimensional materials have opened new perspectives to the nanophotonics community with potential applications in metamaterials, modulators, photodetectors, and sensors. After having a short introduction of the 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, plasmonics-laser-color printing, and graphene for optoelectronic applications. Then, I will mainly discuss plasmons in two-dimensional materials and show how to explore these materials 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.

个人简介：Sanshui Xiao obtained his PhD degree at Zhejiang University in 2004. Then he joined Min Qiu’s group at the Royal Institute of Technology as a post-doc researcher. In 2006, he started to work at the Technical University of Denmark, and in 2011 he tenured as Associate Professor there. His current research interests include exploration of fundamental physics of light-matter interactions at the nanoscale and development of two-dimensional-materials-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.
