Optical metasurfaces and metamaterials：

Optical metasurfaces and metamaterials have been the focus of optical research in the past two decades. Specially designed optical structures can be used to achieve some exotic optical properties, such as negative refractive index and strong chirality; some complex and flexible optical functions can also be realized, such asHolography, multifunctional polarization modulation, etc.

Micro-Nano Photonics：

Study the interaction of light and matter at the micro/nano scale.
