Abstract Metasurfaces are nanopatterned structures of sub-wavelength thickness. Their effective refractive index and spectral characteristic can be tailored by material composition, intrinsic and extrinsic resonances, structure size, and ambient conditions. Consequently, they allow for phase, amplitude, polarisation, and spatial control of an optical field beyond what natural materials can offer. Dielectric metasurfaces with lower loss have opened a wide range of new applications such as enhanced imaging, structural colour, holography, and planar sensors. In particular, beam steering and control measures such as nonlinear optics, ultrafast optics, and quantum optics are of increasing importance for quantum communication, computation, and information processing. In this review, the recent progress on dielectric metasurfaces is summarised, including advanced fabrication technologies and novel applications from advanced wavefront shaping to quantum platforms. In addition, a perspective for the future development of the field is presented.

介电超表面：从波前整形到量子平台

摘要 超表面是亚波长厚度的纳米图案结构。它们的有效折射率和光谱特性可以通过材料成分、内在和外在共振、结构尺寸和环境条件进行定制。因此，它们允许对光场进行相位、幅度、偏振和空间控制，超出了天然材料所能提供的范围。具有较低损耗的介电超表面开辟了广泛的新应用，例如增强成像、结构颜色、全息和平面传感器。特别是非线性光学、超快光学和量子光学等光束转向和控制措施对量子通信、计算和信息处理的重要性日益增加。在这篇综述中，总结了介电超表面的最新进展，包括先进的制造技术和从先进的波前成形到量子平台的新应用。此外，还提出了对该领域未来发展的展望。
