Welcome to the Nanoscale and Quantum Photonics Research Group
Our research is focused on the nanoscale and quantum photonics and low-dimensional quantum materials, with particular interest in the fundamental physics related to the nanoscale cavity-mediated light-matter interaction in the quantum regime, including quantum plasmonics, molecular electronic plasmonics, nonlinear nanophotonics, exciton polariton physics and devices. These fundamental studies are relevant to many exciting applications in miniaturized photonic and optoelectronic devices, energy harvesting, conversion, storage and saving, advanced biochemical sensing and biomedical imaging. We have direct access to a large number of advanced optical measurement systems for single-particle absorption / scattering, reflection / transmission, fluorescence and Raman spectroscopies, with functionalities ranging from near- to far-field, linear to nonlinear, steady state to time-resolved and ultrafast regimes.
