论文摘要
我们表明，通过将光学跨膜的极端多功能性和自由控制与光子整合电路的紧凑性相结合，可以通过将极端的多功能性和自由度结合到光前控制的极端多功能性和自由度来产生任意复杂的光场。我们通过我们的元表面光子集成设备展示了片外2D聚焦和全息投影。这项技术具有许多其他光学应用的潜力，这些光学应用需要2D光场操作，并具有完整的芯片集成，例如固态雷达和近眼AR/VR显示器。
We show that a metasurface-coated two-dimensional (2D) slab waveguide enables the generation of arbitrary complex light fields by combining the extreme versatility and freedom on wavefront control of optical metasurfaces with the compactness of photonic integrated circuits. We demonstrated off-chip 2D focusing and holographic projection with our metasurface-dressed photonic integrated devices. This technology holds the potential for many other optical applications requiring 2D light field manipulation with full on-chip integration, such as solid-state LiDAR and near-eye AR/VR displays.
