我们提出了一种新的等离子体超表面，用于同时检测入射光的偏振和光谱。所展示的超表面是一个合理设计的人造原子簇，它被设计成具有偏振和波长选择性的光传输。该结构的基本组成部分是具有不同取向和晶格常数的周期性耦合亚波长孔径阵列。当与像素化光电探测器集成时，超表面可以用来测量光输入的偏振和光谱信息。在这篇论文中，通过分析通过超表面的透射强度分布，实验证明了同时检测偏振光的偏振和光谱。所展示的超表面为许多应用提供了巨大的潜力，例如偏振多光谱成像和光通信中的偏振分复用。
We present a new plasmonic metasurface for simultaneous detection of polarization and spectrum of incident light. The demonstrated metasurface is a rationally designed cluster of artificial atoms that are engineered to exhibit polarization and wavelength-selective optical transmission. The fundamental building block of this structure is periodically coupled subwavelength aperture arrays with different orientations and lattice constants. When integrated with pixelated photodetectors, the metasurface can be used to measure the polarization and spectral information of an optical input. In this Letter, simultaneous detection of the polarization and spectrum of polarized light was experimentally demonstrated by analyzing the transmitted intensity distribution through the metasurface. The demonstrated metasurface offers great potential for many applications, such as polarimetric multispectral imaging and polarization-division multiplexing in optical communications.
