Dynamic Control of Phase Matching in Nonlinear Metasurfaces Using Pancharatnam–Berry Phase

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Can mechanical rotation of a metasurface control the phase of a nonlinear optical signal? In a dual‐metasurface multipass cell, a circularly polarized pump interacts repeatedly with two plasmonic metasurfaces between two mirrors. By exploiting the geometric phase, rotating one metasurface shifts the phase‐matching condition of the second‐harmonic ...

Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
A silicon photonic beam steerer based on a metalens focal plane array (FPA) monolithically integrates the collimation lens on‐chip while enabling blind‐spot‐free continuous beam steering. Thermo‐optic prisms provide continuous fine‐tuning and more than double the number of resolvable points.

Rolling‐Enabled Nonplanar Heterogeneous Integration for Polarization‐Diverse Nanolasers on Silicon Photonics

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Rolling‐enabled transfer printing introduces mechanical orientation as a new degree of freedom for heterogeneous silicon photonics. A conventional TE‐like photonic‐crystal nanobeam laser is mechanically rotated by 90° to selectively couple with the TM‐like mode of a silicon waveguide, enabling polarization‐diverse functionality without redesigning the ...

Spiro‐Phenothiazine Hole‐Transporting Materials: Unlocking Stability and Scalability in Perovskite Solar Cells

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
