Metalens-based miniaturized optical systems
Web6 apr. 2024 · Abstract. Extreme ultraviolet (EUV) radiation is a key technology for material science, attosecond metrology, and lithography. Here, we experimentally demonstrate metasurfaces as a superior way to focus EUV light. These devices exploit the fact that holes in a silicon membrane have a considerably larger refractive index than the surrounding ... Web12 feb. 2024 · In this study, a tunable all-dielectric metalens (TADM) is presented. Focal lengths of incident wavelengths could be tuned by vertically changing the distance between two metalens layers or changing the incident angle of light. By changing the distance between two metalens layers from 5 μm to 32 μm, the tuning ranges of focal lengths are …
