Polaritons are hybrid excitations of matter and photons. In recent years, polaritons in van der Waals nanomaterials—known as van der Waals polaritons—have shown great promise to guide the flow of light at the nanoscale over spectral regions ranging from the visible to the terahertz. A vibrant research field based on manipulating strong light–matter interactions in the form of polaritons, supported by these atomically thin van der Waals nanomaterials, is emerging for advanced nanophotonic and opto-electronic applications. Here we provide an overview of the state of the art of exploiting interface optics—such as refractive optics, meta-optics and moiré engineering—for the control of van der Waals polaritons. This enhanced control over van der Waals polaritons at the nanoscale has not only unveiled many new phenomena, but has also inspired valuable applications—including new avenues for nano-imaging, sensing, on-chip optical circuitry, and potentially many others in the years to come.

与范德华极化子的界面纳米光学

极化子是物质和光子的混合激发。近年来,范德华纳米材料中的极化子(称为范德华极化子)已显示出在从可见光到太赫兹的光谱区域内引导纳米级光流的巨大希望。基于以极化子形式操纵强光-物质相互作用的充满活力的研究领域,在这些原子级薄范德华纳米材料的支持下,正在为先进的纳米光子和光电应用而兴起。在这里,我们概述了利用界面光学技术(例如折射光学、超光学和莫尔工程)来控制范德华极化子的最新技术。这种在纳米尺度上对范德华极化子的增强控制不仅揭示了许多新现象,
