Metasurfaces have introduced new opportunities in photonic design by offering unprecedented, nanoscale control over optical wavefronts. These artificially structured layers have largely been used to passively manipulate the flow of light by controlling its phase, amplitude, and polarization. However, they can also dynamically modulate these quantities and manipulate fundamental light absorption and emission processes. These valuable traits can extend their application domain to chipscale optoelectronics and conceptually new optical sources, displays, spatial light modulators, photodetectors, solar cells, and imaging systems. New opportunities and challenges have also emerged in the materials and device integration with existing technologies. This Review aims to consolidate the current research landscape and provide perspectives on metasurface capabilities specific to optoelectronic devices, giving new direction to future research and development efforts in academia and industry.
超表面通过对光波前提供前所未有的纳米级控制，在光子学设计中带来了新机遇。这些人工构造的层主要用于通过控制光的相位、幅度和偏振来被动地操纵光流。然而，它们也能够动态地调制这些量，并操纵基本的光吸收和发射过程。这些宝贵特性可将其应用领域扩展到芯片级光电子学以及概念上全新的光源、显示器、空间光调制器、光电探测器、太阳能电池和成像系统。在材料以及与现有技术的器件集成方面也出现了新的机遇和挑战。本综述旨在巩固当前的研究状况，并就光电器件特有的超表面能力提供观点，为学术界和工业界未来的研发工作指引新方向。
