High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

Smart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

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 ...

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

Nanophotonics, 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

Nanophotonics, 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

Nanophotonics, 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.
