Planar Super‐Oscillation Diffractive Lenses: Practical Developments and Applications

open access: yesNanophotonics, 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 ...

Temperature Dependent Complex Refractive Index (CRI) of Hexagonal Ice in the Range 150–270 K: Infrared and Far‐Infrared Transmission Measurements at the AILES Beamline

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The complex refractive index (CRI) of ice is one of the main parameters driving the optical properties of ice clouds and frozen surfaces, hence their climate impact. While already characterized at short wavelengths, ice CRI has never been measured across the infrared range at temperatures relevant to Earth.

Band‐Selective, Low‐Dispersion Terahertz Attenuators Based on 3D Bulk Metamaterials Leveraging De‐latticed Cross‐Bar Resonator Ensembles

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
This paper presents 3D bulk metamaterials in which diced cross‐bar meta‐grains are randomly dispersed in a polymer matrix by molding. The de‐latticed composite provides isotropic and band‐selective THz attenuation with over tenfold dispersion suppression compared to the periodic metasurface.

Ultrasound Participated Optomechanical Frequency Comb Generation and Tunability in High‐Q Microbubble Cavities

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
Optomechanical frequency combs are generated in high‐Q microbubble cavities by simultaneous ultrasound and laser excitation, arising from nonlinear coupling between optomechanical modes and ultrasonically driven mechanical oscillations. Comb spacing and intensity are tunable through acoustic and optical parameters, whereas the optical spring effect ...

Ultra‐Broadband Optical Characterization of TiO2 Nanotube Arrays Revealing Annealing‐Tunable THz Absorption

open access: yesNanophotonics, Volume 15, Issue 15, 13 August 2026.
Lithography‐free spaced TiO2 NT arrays unlock tunable broadband absorption from THz to UV. By harnessing annealing‐driven phase transitions, strong phonon–polariton resonances emerge in the 1.4–3.6 THz range, whereas high absorptance persists beyond 10 THz.
