| 报告介绍 | 报告摘要：
Detection and manipulation of single quantum system with light have been of great interest in the past two decades because of their importance in fundamental studies as well as in emerging applications, ranging from physical chemistry, spectroscopies, metrology and quantum information processing. In this talk, I will present our recent efforts in achieving controllable and efficient interaction between light and a single molecule with optical antennas. In the first part, I will talk about how to use antennas as our “nano-finger” to efficiently excite the molecule and manipulate its emission for ultrafast emission rate and high directivity without invoking quenching. In the second part, I will discuss coherent interaction of a single molecule and a metallic nanostructure. I will show extreme situations where the molecule could modify the response of our “nano-finger” (antenna) by a great deal, i.e. completely diminish its large extinction cross section or enhance its absorption by thousand times.
报告人简介：
Dr. Xuewen Chen is currently with the Max-Planck Institute for the Science of Light (MPL) and Universität Erlangen-Nürnberg (FAU), Erlangen Germany. Dr. Chen received his Bachelor in the Mixed Class of Chu Kochen Honors College in 2003 and Ph.D degree in Optical Engineering in 2008, both from Zhejiang University, China. During his Ph.D studies, Dr. Chen spent two years in the University of Hong Kong and the Hong Kong Polytechnic University on research projects related to organic light-emitting devices. After graduation he worked as a postdoctoral fellow in the Laboratory of Physical Chemistry in Swiss Federal Institute of Technology Zurich (ETH, Zurich) until July 2011. Since then he has been working towards Habilitation at MPL and FAU in Erlangen, Germany. His main research interest is studying classical and quantum aspects of light-matter interactions at the nanoscale, including nanoplasmonics, single-molecule spectroscopies, coherent ultrafast phenomena, single-photon sources and related photonic quantum information processing systems. |
