Metasurfaces are recently incorporated with waveguides for in-plane wave manipulation and extraction, enhancing the capability and design flexibility of integrated photonic devices. However, the unique guided-wave-driven scheme poses challenges in achieving multiplexed functionality for on-chip integrated metasurfaces. Here, an on-chip direction-multiplexing strategy is proposed and demonstrated for high-capacity 3D multiplane projection in free space. By exploring and utilizing the direction-dependence of the guided-wave-driven detour phase manipulation, a 16-channel on-chip holography is realized with different images independently encoded at distinct z planes for all four illumination directions. Moreover, the on-chip full-space 3D holography is demonstrated by exploiting the conjugated relation of the optical responses driven by the opposite on-chip illuminations, enabling observation of a total of 16 holographic images in full-space. The demonstrated on-chip direction-multiplexed holography exhibits low background noise or crosstalk and offers high information density and quality, which shows promise for practical applications in data storage, 3D display, and virtual/augmented reality.

用于大容量 3D 全息的片上方向复用元光学器件
超表面最近与波导相结合，用于平面内波操纵和提取，增强了集成光子器件的功能和设计灵活性。然而，独特的导波驱动方案对实现片上集成超表面的复用功能提出了挑战。这里，提出并演示了一种片上方向复用策略，用于自由空间中的高容量 3D 多平面投影。通过探索和利用导波驱动绕行相位操纵的方向依赖性，实现了 16 通道片上全息术，在所有四个照明方向的不同z平面上独立编码不同图像。此外，通过利用相反片上照明驱动的光学响应的共轭关系，演示了片上全空间 3D 全息术，从而能够在全空间中观察总共 16 个全息图像。所演示的片上方向复用全息术具有低背景噪声或串扰，并提供高信息密度和质量，这在数据存储、3D 显示和虚拟/增强现实等实际应用中展现了前景。
