报告内容：
超表面（Metasurface）是一种基于纳米光学技术，由周期性纳米结构组成的超薄二维阵列平面。通过控制纳米结构的形状，大小，间距以及结构设计，可实现对入射光波的相位，偏振的任意调控。其高精度的光学调控能力，高集成度，微型化等诸多优点使基于超表面的新型光学器件在光束偏转，多功能透镜，复杂矢量光束生成，偏振控制，全息成像等研究领域呈现出广泛的应用前景。本次报告首先简要介绍超表面（metasurface）的基本原理及加工工艺。然后重点介绍基于超表面的新型器件设计与实现，包括偏振测量，可调全息实现，偏振可控的多通道涡旋光束叠加，以及复杂偏振控制。
Optical metasurfaces, the engineered interfaces consisting of metal or dielectric nanopatterns, have drawn considerable attention in the scientific community due to their exotic electromagnetic properties and breakthroughs for light phase and polarization manipulation. Metasurface has been widely adopted in many applications such as lensing, beam steering, polarization control, and holograms. In this talk, the theoretical background and fabrication process about metasurface will be introduced firstly. Then the metasurface devices with novel functionalities, such as polarization measurements, helicity multiplexed holograms, and polarization controlled superposition of orbital angular momentums, will be demonstrated and discussed.
