Abstract

We report the design and anticipated fabrication of Germanium metalenses on Ge and ZnSe platforms in the long-wavelength infrared (12–15 µm). Integrated into indirect absorption spectroscopy systems, they enable miniaturization for BTEX detection (Benzene, Toluene, Propane), addressing the need for compact optical components in the LWIR range.
