Abstract:
In this talk, I will give an overview of the applications of metamaterials and plasmonics with a special focus on the design of optical metamaterials and plasmonic light harvesting devices. Special emphasis will be given on the new frontier of the metamaterial/plasmonic research where the geometrical features of the devices are approaching the subnanometer regime and the nonlocal and quantum effects play a vital role. I will introduce a simple and efficient model able to describe the nonlocal and quantum nature of metallic electrons at the nanoscale. This model enables the design of large-scale plasmonic systems with Angstrom-sized geometrical features. As an example, I will show how this model can be used to design practical nanophotonic devices for sub-diffraction-limited imaging and high-harmonic generation. These studies are crucial for the experimental nano-optics in the miniaturization trend.
About the Speaker:
Dr Yu LUO received his B.S. in Electronic Information Engineering from Zhejiang University in 2006 and Ph.D in Physics from Imperial College London in 2012. He was then employed as a research associate in the same institution. Since January 2015 Luo has been an assistant professor in the School of Electrical and Electronic Engineering, Nanyang Technological University. Luo has worked on a wide range of topics within the realm of metamaterials and plasmonics ranging from the design of invisibility cloaks and plasmonic light-harvesting devices to the study of nonlocal and quantum phenomena in mesoscopic metamaterial/plasmonic systems. He has authored and coauthored 46 papers in international refereed journals, including Nature Physics, Nature Communications, PNAS, PRL, Nano Lett., and Adv. Mater.. These articles have received over 1,000 citations. His work has been highlighted by many scientific magazines and public media, including Nature Photonics, Nature Physics, Physics World, Phys.org, BBC News, Guardian, etc.
