论文摘要
许多现代应用程序，例如娱乐显示，数据加密，安全性和虚拟现实（VR）技术，都需要不对称的光操作。对称自旋 - 轨道相互作用（SOI）在实现不对称元数据时应用了一个限制。然而，不同的不对称SOI基于传播和几何相融合技术有效地打破了这一限制，以设计复杂性和更高的计算成本为代价。这项工作提出了一种新颖的螺旋多路复用技术，它破坏了实现双轴双侧全息图的所有上述障碍。受益于各向异性纳米共鸣天线的几何相调制，我们采用了单个单位细胞来实现螺旋性多路复用。低灭绝系数材料A-SI：H用于设备分析。由于简单的基于单位单元的设计技术，模拟和制造复杂性大大降低。结果，基于电磁波的螺旋性和入射方向，我们在可见的频带中实现了高度传播的双全息图像。我们的模拟效率为蓝色（λ= 488 nm），绿色（λ= 532 nm）和红光（λ= 633 nm）的55％，75％和80％。
Many modern applications like entertainment displays, data encryption, security, and virtual reality (VR) technology require asymmetric light manipulation. Symmetric spin-orbit interactions (SOI) apply a limit in achieving an asymmetrical metahologram. However, different reported asymmetric SOI's based on propagation and geometric phase mergence techniques effectively break this limit at the expense of design complexity and greater computation cost. This work proposes a novel helicity multiplexing technique that breaks all the aforementioned barriers in achieving on-axis dual side holograms. Benefiting from the geometric phase modulation of anisotropic nano-resonating antennas, we have employed a single unit cell to achieve helicity multiplexing. A low extinction coefficient material a-Si:H is used for device analysis. Due to the simple single unit cell-based designing technique, simulation and fabrication complexities were significantly reduced. As a result, based on the helicity and incidence direction of electromagnetic wave, we have achieved highly transmissive dual holographic images in the visible band. Our simulated efficiencies are 55%, 75%, and 80% for the blue (λ = 488 nm), green (λ = 532 nm), and red light (λ = 633 nm).
