Wafer‐Scale Manufacturing of Near‐Infrared Metalenses (Laser Photonics Rev. 18(4)/2024)

In article 2300929, Junsuk Rho and co-workers present two scalable methods for manufacturing near-infrared metalenses.The first method produces a 1 cm diameter, 0.53 numerical aperture (NA) polarization-independent metalens composed of hydrogenated amorphous silicon.The second method creates a 5 mm diameter, 0.53 NA polarizationdependent metalens composed of silicon-nanoparticle-embedded resin.Both metalenses exhibit high-resolution imaging capabilities, making significant progress in metalens production and optical technology.
