Abstract

A comprehensive manipulation of the Jones matrix phase channels is crucial for enhancing the information capacity and security of the metasurface. However, a single-layer planar metasurface, without the incorporation of chirality, can only achieve a maximum of three independent phase channels for single Jones matrix under either linear or circular polarization bases. Here, an effective strategy is proposed that utilizes dual Jones matrices in different polarization bases with a single-layer monoatomic metasurface, thus extending the number of independent phase channels to six. To encode six holographic images into these six phase channels, a three-step gradient descent algorithm is introduced. As a proof of principle, a metasurface consisting of arrays of monoatomic dielectric structure is designed and fabricated in each unit cell, which exhibits six independent holographic images in the far field. The demonstrated metasurface platform is expected to open up new possibilities for the development of optical devices for applications in high-capacity information storage, high-security encrypted communication, and high-solution optical displays.

基于单层单原子超表面的双琼斯矩阵六相通道调制
对琼斯矩阵相位通道的综合处理对于提高元表面的信息容量和安全性至关重要。然而,在不引入手性的单层平面超表面下,无论是线性极化基还是圆极化基,单个琼斯矩阵最多只能获得三个独立的相位通道。本文提出了一种利用不同极化基的双琼斯矩阵和单层单原子超表面的有效策略,从而将独立相通道的数量扩展到6个。为了将6张全息图像编码到这6个相位通道中,引入了一种三步梯度下降算法。作为原理证明,设计并制作了一个由单原子介电结构阵列组成的超表面,在远场显示出6个独立的全息图像。所展示的超表面平台有望为开发用于高容量信息存储、高安全性加密通信和高分辨率光学显示的光学设备开辟新的可能性。
