Design of Large‐Aperture Hybrid Refractive Metalens System
Nanophotonics, Volume 15, Issue 18, 25 September 2026.An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.Abstract Top‐down studies of methane (CH4) emissions often use the average ethane‐to‐methane (C2/C1) ratio of wellhead gas in a basin to attribute emissions to thermogenic or biogenic sources. Biogenic CH4 sources (ruminants, wetlands, landfills, and other methanogenic sources) do not co‐produce ethane (C2H6); the presence of C2H6 indicates a ...

Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array
Nanophotonics, Volume 15, Issue 17, 11 September 2026.A silicon photonic beam steerer based on a metalens focal plane array (FPA) monolithically integrates the collimation lens on‐chip while enabling blind‐spot‐free continuous beam steering. Thermo‐optic prisms provide continuous fine‐tuning and more than double the number of resolvable points.
