Abstract: The present application discloses a method for preparing optical metasurfaces, wherein the method is performed based on nano-imprinting, and the template used in the method is an imprinting template with patterns of meta-atoms. The method for preparing optical metasurfaces provided by the present application can replace the electron beam lithography method used in fabricating meta-atoms, greatly reducing the costs, and greatly reducing the production time. The method provided by the present application significantly improves the production cost and the production time, achieving a low-cost, large-scale fabrication of metasurface-based optical elements within a short time, and having good industrialization prospects.
