研究领域

纳米光子学与表面等离子体光子学(Nanophotonics and Plasmonics) 光与物质相互作用是自然界最基本的相互作用之一,近年来对其研究的尺度已经从宏观不断向微观扩展,并发展出了纳米光子学等学科,其相关应用已经涵盖光学传感、通讯传输、医疗诊断及量子操控等多个方面。基于表面等离子体共振效应(Surface Plasmon Resonance)所构建的金属纳米结构, 能够突破光的衍射极限,将电磁场的能量局限到纳米尺度,实现光与物质相互作用的指数级增强与放大。 极端纳米光子学(Extreme Nanophotonics): 通过构建金属纳米间隙的光腔结构(Plasmonic Nanogap),我们能够将表面等离子体共振的光场调控效果推向极致:光场被局域到几个纳米或亚纳米尺度的间隙中,从而产生极大的电磁场增强。这使得间隙中纳米材料的光与物质相互作用极大增强,并成为许多前沿研究与应用的物理基础,包括单分子表面增强光谱、增强非线性、生物传感、光催化、光与物质强耦合、片上光芯片、分子腔光力学等。
