Our Laboratory More

We are a vibrant and development potential research group in nanophotonics. Based on a multi-dimensional experimental platform for nanoscopic optical characterization, we have long been engaged in research related to near-field optics, plasmonics, and nanophotonic materials and devices.

Research Interests

1. Cathodoluminescence (CL) spectroscopy

2. Ultrafast optics and Excitonic physics

3. Interfacing Nanophotonics with Artificial Intelligence

4. Industry-university Research: photoelectric chip
