报告摘要 (Abstract)：

研究并控制光与物质相互作用是现代光学科学的核心，寻找带有新颖性能的材料并在此基础上发展新功能器件是其中一个重要课题。在这个背景下，光子晶体和超材料、超表面提供了一个通过人工设计产生新光学性能的途径，同时，新兴的二维材料也提供了新的光学平台。这个报告将简要讨论如何通过多物理耦合将二维材料和超材料结合，从而产生新颖的光学平台，并讨论其在非线性、激子激元、声子激元等方面的应用。

Studying and manipulating the light-matter interactions are central in modern optics. Exploring the exotic functional optical materials and establishing new devices are one of its most important topics. In this background, photonic crystals, metamaterials, and metasurfaces have provided a new pathway towards novel optoelectronic platforms via the artificial structuring. Meanwhile, the emerging low-dimensional natural nanomaterials also offer exciting optical properties. In this talk, I will briefly discuss how to connect different physics of low-dimensional natural materials with metamaterials and metasurfaces to develop the novel Multiphysics photonic platforms. I will also discuss their enabling applications in nonlinear optics, plasmonics, phonon polaritonics and other fields.
