中文摘要： 纳米光子结构中基于光学力的光机械诱导非线性现象为弱光非线性的实现提供了一条新的途径。最近，超材料中光学力的研究和机械可重构超材料的发展为非线性光机械超材料的实现提供了可能。本课题在我们前期工作基础上，拟以低损耗的平面介质超材料为对象，旨在:（1）通过三维电磁仿真技术，研究介质超材料中近场共振光学力的产生与增强机制，优化光机械超材料的设计；（2）探索和完善光机械超材料纳米加工工艺；（3）从实验上证明光机械超材料中基于光学力的光机械诱导非线性现象。从而为深入研究超材料中基于光学力的光-机械相互作用机理和光机械诱导透明等物理现象打下坚实的理论和实验基础。本课题的开展有助于深化人们对纳米尺度下光与物质相互作用的理解，对于非线性/可重构超材料的研究，以及自适应光子器件、光机械记忆器件等纳米光子学功能器件的开发有着重要的意义。

英文摘要： Optomechanically induced nonlinearity through optical forces in nanophotonic structures provides a new route for the realization of optical nonlinearity at low intensities. Recently, the study of optical forces in metamaterials and the development of mechanically reconfigurable metamaterials pave the way for nonlinear optomechanical metamaterials. On the basis of our prior work, this project makes use of low-loss planar dielectric metamaterials and aims to: (1) Study the mechanism for generation and enhancement of resonant near-field optical forces in dielectric metamaterials and optimize the design of optomechanical metamaterials using three-dimensional electromagnetic numerical simulations; (2) Explore and improve the nanofabrication methods for optomechanical metamaterials; (3) And experimentally demonstrate optomechanically induced nonlinearity in optomechanical metamaterials, which will provide solid theoretical and experimental foundation to study the optical-mechanical interactions through optical forces in metamaterials as well as related physical phenomena such as optomechanically induced transparency in depth. This project will enhance our understanding of light-matter interactions in the nanoscale and is of great significance for the research of nonlinear/reconfigurable metamaterials and the developme
