Abstract

Janus Metasurfaces with Arbitrary Polarization Control

The first Janus metasurfaces demonstrate directionally asymmetric orbital angular momentum generation from arbitrary spin. Titania-based meta-atoms enable operation in the visible range, extending beyond prior demonstrations in microwave and mid-infrared regions. Meta-atoms provide local/global rotation and width control, achieving global directional multifunctionality tailored by the Jones matrix. This multifunctionality in a single-layer design surpasses previous approaches based on spatial multiplexing or vertical stacking, expanding its applicability across diverse domains. For further details, see article number 2401335 by Yao-Wei Huang and co-workers.

利用单层电介质 Janus 元表面生成方向不对称的轨道角动量（先进光学材料 31/2024）

具有任意偏振控制功能的杰纳斯元表面首个杰纳斯元表面展示了任意自旋产生的方向不对称轨道角动量。基于钛的元原子可在可见光范围内运行，超越了之前在微波和中红外区域的演示。元原子提供局部/全局旋转和宽度控制，实现了由琼斯矩阵定制的全局定向多功能性。这种单层设计的多功能性超越了以往基于空间多路复用或垂直堆叠的方法，扩大了其在不同领域的适用性。更多详情，请参阅黄耀伟及其合作者的 2401335 号文章。
