Light Makes Our Life Shine

Our group is dedicated to understanding the interaction between light and matter at the nano- and micro-scales, and to discovering new light-related phenomena.

​

Based on these novel light phenomena, our mission is to develop new photonic materials and the next generation of optoelectronics, contributing to fields such as energy, security, sensing, bio-medical devices, and imaging systems.

​

Specifically, our research ranges from the level of photonic materials (e.g., nanophotonics and metasurfaces) to optical devices and systems (e.g., energy-saving systems and bio-inspired imaging systems).

​

We envision a future society enriched with safety and prosperity, driven by advancements in light-related technologies.
