Flat Optics for edge imaging and polarimetric imaging

这是一个物理学博士研究项目。近年来，由平面纳米结构组成的出射光子器件在光传输控制方面显示出了前所未有的前景。光学超颖表面是一种平面纳米结构界面，由于其在亚波长尺度上控制光的振幅、相位和偏振的能力，近年来引起了人们极大的兴趣。平面光学为具有特殊功能的MEMS器件的发展提供了新的机会，这是器件小型化和系统集成的理想选择。该项目将集中在亚波长尺度上的相位和偏振的同时控制，并开发用于边缘成像和偏振成像的新型设备。

This is a PhD research project in Physics. Recently, the emergent ultrathin optical devices consisting of planar nanostructures have shown much promise for unprecedented control of light propagation. Optical metasurfaces are planar nanostructured interfaces and have recently attracted tremendous interests due to their capability in the manipulation of the amplitude, phase and polarization of light at subwavelength scale. Flat optics has provided new opportunities for the development of ultrathin devices with unusual functionalities, which are ideal for device miniaturization and system integration. This project will concentrate on the simultaneous control of phase and polarisation at subwavelength scales and develop novel devices for edge imaging and polarimetric imaging.
