Visible Meta‐Displays for Anti‐Counterfeiting with Printable Dielectric Metasurfaces
Metasurfaces, 2D arrays of nanostructures, have gained significant attention in recent years due to their ability to manipulate light at the subwavelength scale. Their diverse applications range from advanced optical devices to sensing and imaging technologies. However, the mass production of dielectric metasurfaces with tailored properties for visible light has remained a challenge. Therefore, the demand for efficient and cost‐effective fabrication methods for metasurfaces has driven the continuing development of various techniques. In this research article, a high‐throughput production method is presented for multifunctional dielectric metasurfaces in the visible light range using one‐step high‐index TiO2‐polymer composite (TPC) printing, which is a variant of nanoprinting lithography (NIL) for the direct replication of patterned multifunctional dielectric metasurfaces using a TPC material as the printing ink. The batch fabrication of dielectric metasurfaces is demonstrated with controlled geometry and excellent optical response, enabling high‐performance light‐matter interactions for potential applications of visible meta‐displays.
