Planar Super‐Oscillation Diffractive Lenses: Practical Developments and Applications

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
This review examines planar super‐oscillation diffractive lenses as a unified framework for super‐oscillatory lenses and supercritical lenses. It focuses on applications in super‐resolution imaging, micro/nanofabrication, and precision measurement and relates their application‐specific requirements to focal‐field control, multiobjective design ...

Third‐Order Nonlinear Optical Response and Optical Limiting in Silver‐Cobalt Bimetallic Nanoparticles

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
Silver‐cobalt bimetallic nanoparticles with a surface Co3O4 layer combine plasmonic field enhancement with interfacial charge transfer to deliver strong reverse saturable absorption and low‐threshold optical limiting under both continuous‐wave and nanosecond excitation.

A GEO‐LEO Imager Data Set for Characterizing Rapid Changes of Global Aerosol Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Aerosols, the ubiquitous small particulates in our atmosphere, have climate, air quality, and/or other impacts far from their original sources. The Dark Target Algorithm (DTA), originally developed for retrieving aerosol properties from satellite imagers in Low‐Earth Orbit (LEO), has been ported to imagers in Geostationary (GEO) orbit. Using a

Ultra Compact and Broadband Fiber Facet Graphene Oxide Microlens Array Fabricated on a Beam‐Expanding Fiber Facet Using Femtosecond Laser Direct Writing Technique

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
A 400 nm graphene oxide film on a beam‐expanding fiber facet is patterned by femtosecond laser direct writing into a 19‐lens microlens array. The device simultaneously splits a single input beam into multiple 0.67–0.74 NA focus spots with a broadband response from 850 to 1550 nm.
