From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Simultaneous ToF/FMCW LiDAR Using a Dual‐Mode Light Source in a Single Architecture

Laser &Photonics Reviews, EarlyView.
A simultaneous ToF/FMCW LiDAR architecture is demonstrated using a dual‐mode light source that alternately generates optical pulses and frequency‐chirped light within a single acquisition. By combining time‐domain ToF and coherent FMCW ranging, the system achieves high‐resolution ranging and velocity sensing while extending the measurable range beyond ...

Nanoscale Rear‐Interface Architecture Enables 36.2 mA cm−2 Photocurrent in Ultrathin and Bifacial ACIGS Solar Cells Through Light Management

Laser &Photonics Reviews, EarlyView.
An array of SiOx nanopillars is developed on ITO transparent rear contacts through nanoimprint lithography to promote light scattering in 500–600 nm bifacial ACIGS solar cells. This architecture increases the short‐circuit current density by 7.8 and 7.6 mA cm−2 under front (up to 36.2 mA cm−2) and rear illumination, respectively, offering a scalable ...

Engineering Photonic Pigments From Titania–Block Copolymer Composites

Macromolecular Rapid Communications, EarlyView.
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.
