Moiré Metamaterials and Metasurfaces

Abstract

Abstract Optical metamaterials and metasurfaces enable versatile light manipulations. Advancements in modeling, nanofabrication, and characterization tools have led to the development of metamaterials and metasurfaces for many applications: energy conversion, biomedicine, and information technology. Recently, metamaterials and metasurfaces with moiré configurations have attracted strong interest due to their highly tunable optical responses and high‐throughput fabrication. Herein, state‐of‐the‐art moiré metamaterials and metasurfaces are reviewed. The presentation covers fabrication techniques, structure–property relationships, and applications in lasing and biomedical sensing. The review concludes with challenges and opportunities for moiré metamaterials and metasurfaces.
