Multi‐Scale Engineering of Photonic Meta‐Structures With Emergent Optical Resonances via Colloidal Crystal Engineering With DNA and Microwell Templates

Small, EarlyView.
This work presents a bottom‐up strategy for forming meta‐structures built from DNA‐assembled nanoparticle superlattices, establishing a versatile platform for multiscale photonic materials design. Confinement stabilizes non‐equilibrium crystal habits and enables geometry and mode control independent of lattice symmetry.

Relative Effects of Fabry‐Perot, Mie, and Guided‐Mode Resonance in Periodic Photonic Lattice Physics

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
The physical origins of resonance effects in one‐dimensional periodic photonic lattices are studied to assess the relative roles of Fabry–Perot, Mie, and guided‐mode resonance mechanisms. It is shown that lattice resonance is fundamentally governed by lateral leaky Bloch modes and their coupling to external radiation via guided‐mode resonance.

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.

Inverse Drexhage Effect in Epsilon‐Near‐Zero Substrates

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Radiative emission of dipoles near substrates is shown to reverse between (a) perfect electric conductors and (b) epsilon‐near‐zero (ENZ) media. The schematic highlights switch from vertical to horizontal dipole dominance, governed by interference with image dipoles, leading to directional emission into the upper half‐space and enabling new strategies ...

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.

Chiral Phase Change Nanomaterials

Advanced Functional Materials, Volume 36, Issue 67, 20 August 2026.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Toward Enhanced Inertial Sensing via Dynamically Soft Topological States in Piezoelectric Microacoustic Metamaterials

Advanced Functional Materials, Volume 36, Issue 62, 3 August 2026.
A piezoelectric microacoustic wave device exploiting topologically protected interface states with significantly higher dynamic compliance than Lamb or Rayleigh modes achieves record‐high out‐of‐plane particle velocities exceeding 51 m/s. These findings indicate that leveraging topological interface states can overcome key limitations of piezoelectric ...
