Abstract With their ultrathin characteristics as well as the powerful and flexible capabilities of wavefront modulation, optical metasurfaces have brought a new understanding of the interaction between light and matter and provided a powerful way to constrain and manage light. However, the unmodifiable structures and the immutable materials used in the construction lead to the unsatisfactory applications in most functional devices. The emergence of tunable optical metasurfaces breaks the aforementioned limitations and enables us to achieve dynamic control of the optical response. The work in recent years has focused on achieving tunability of optical metasurfaces through material property transition and structural reconfiguration. In this review, some tunable optical metasurfaces in recent years are introduced and summarized, as well as the advantages and limitations of various materials and mechanisms used for this purpose. The corresponding applications in functional devices based on tunability are also discussed. The review is terminated with a short section on the possible future developments and perspectives for future applications.

由多种调制机制实现的可调谐光学超表面

摘要 光学超表面以其超薄的特性以及强大而灵活的波前调制能力，使人们对光与物质之间的相互作用有了新的认识，并提供了一种有效的光约束和管理方法。然而，结构中使用的不可修改的结构和不变的材料导致在大多数功能设备中的应用不尽如人意。可调谐光学超表面的出现打破了上述限制，使我们能够实现光学响应的​​动态控制。近年来的工作重点是通过材料特性转换和结构重构来实现光学超表面的可调谐性。在这篇综述中，介绍和总结了近年来的一些可调光学超表面，以及用于此目的的各种材料和机制的优点和局限性。还讨论了基于可调谐性的功能器件中的相应应用。审查以关于未来可能的发展和未来应用前景的一小部分结束。
