摘要:

超颖表面是二维光学结构,能够完全控制光的振幅、相位和偏振。与等离子体超颖表面不同,平面硅结构有利于高传输、低损耗以及与现有半导体技术的兼容性。在这里,我们报告了在电信波长的传输模式下具有全2pi相位控制的高效率偏振敏感电介质超颖表面的实验演示。这样的硅超颖表面有望实现一个多功能的光学平台,在芯片上实现全光学电路。

英文摘要:

Metasurfaces are two-dimensional optical structures enabling complete control of the amplitude, phase, and polarization of light. Unlike plasmonic metasurfaces, planar silicon structures facilitate high transmission, low losses and compatibility with existing semiconductor technologies. Here, we report an experimental demonstration of high-efficiency polarization- sensitive dielectric metasurfaces with full 2pi phase control in transmission mode at telecommunication wavelengths. Such silicon metasurfaces are poised to enable a versatile optical platform the realization of all-optical circuitry on a chip.
