用于同时光聚焦和偏振操纵的薄各向异性超颖表面

A thin anisotropic metasurface for simultaneous light focusing and polarization manipulation

Mehdi Veysi, Ozdal Boyraz, Filippo Capolino

摘要:

集成两种重要类别的光学元件的可能性,即,圆偏振器和透镜,到一个薄的等离子体超颖表面进行检查。在探索了一般理论公式后,在金属损耗不能忽略的情况下,给出了实现中红外波段偏振透镜的优化设计。具有偏振相关和空间变化相位响应的Y形纳米天线的二维阵列是这种独特的紧凑型偏振透镜的基础,其性质可以在集成光学中具有很高的影响。

英文摘要:

The possibility of integration of two important categories of optical components, i.e., circular polarizer and lens, into a thin plasmonic metasurface is examined. After exploring general theoretical formulation, optimal designs to realize polarizing lenses at mid-infrared frequencies are presented, for the cases when metal losses cannot be neglected. A two-dimensional array of Y-shaped nanoantennas with polarization dependent and spatially varying phase response is the basis for such a unique compact polarizing lens, whose properties can have a high impact in integrated optics.
