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 plasmonics and metamaterials are mainly concerned. To keep pace with the ever increasing information processing, we are aiming to develop new types of the on-chip photonic integrations and disruptive optical devices.  

Notice:Our group welcome new members including Post-doctors, graduate and undergraduate students. Please contact us:
