超表面光场自旋选择多维联合调控研究

Realizing spin-selective manipulation of optical waves plays a key role in the development of modern optics, which will actively promote the development of information optics, quantum optics, singular optics and the design of integrated optical devices. In this project, we will theoretically and experimentally study the implementation of spin-selective multidimensional manipulation of optical waves with metasurfaces. We will study and reveal the underlying physical mechanism of the spin-selective optical response in the new designs (such as few-layer, folded and complementary structures) of artificial nanostructures, study and obtain a general design method for the realization of spin-selective multidimensional manipulation of optical waves in metasurfaces. We will utilize the deep learning technology to realize the reversal design of metasurfaces, which will provide a new and automated approach to the realization of spin-selective multidimensional manipulation of optical waves in metasurfaces. We will further investigate and explore the application of spin-selective multidimensional manipulation of optical waves in quantum optics, information optics and other fields. We will investigate integrated multi-functional optical devices that can be used in optical anti-counterfeiting and multi-channel hologram. We will also investigate integrated quantum optical devices that can realize photon spin-orbit interaction in multiple degrees of freedom. We hope to promote the development of metasurfaces on the area of optical wave manipulation, and form our own characteristics and advantages in the international research field by carrying on this project.
