Welcome to the website of  Prof. Tao Li's research page!
We hope that you can take this chance to look around and find something interesting and informative.

Our research is dedicated to exploit new optical phenomena and the underlying physics in micro/nanoscale from viewpoints of classical and quantum, where the surface plasmon is mainly concerned due to the strong field confinement and enhancement. To keep pace with the ever increasing information processing, we are also developing new type of ultra-compact plasmonic devices towards the on-chip nanophotonic integrations. 

Prof. Tao LI (李涛), received his PhD degree in Physics in NJU, 2005. He joined CEAS of NJU in 2008, and was promoted to full professor in Dec. 2013. He was selected to "Dengfeng Talent Program B" of NJU in 2012, and won the "National Funds for Outstanding Young Scientists" and "K.C. Wong Education Foundation" in 2013.  Up to date, he has published more than 80 peer-reviewed journal papers (including Nature Nanotech., Nature Comm., Phys. Rev. Lett., Nano Lett., Light Sci. Appl., Laser Photon. Rev., etc), which received more than 2100 citations with a current H-index of 26 (Web of Science).
