Robust Chiral High‐Q Response Driven by Quasi‐Bound Flatband in the Continuum
This work theoretically proposes and numerically realizes chiral flatband quasi‐BICs by engineering four counterpropagating folded guided modes. The chiroptical response arises from destructive interference of two antiphase intrinsic modes, and the flatband originates from the interactions among opposite curvature hybrid guided modes.

Suppressing Stitching Errors in Full‐Sensor‐Plane Color Routers via Optical Structural Similarity
Angle‐specific nanophotonic color routers are assembled from a library of inverse‐designed unit cells matched to local incidence angles. Optical structural similarity (OSS) constrains neighboring permittivity profiles during optimization, suppressing inter‐cell stitching errors without additional full‐wave simulations and enabling oblique‐incidence ...

Transition Metal Dichalcogenide Multijunction Solar Cells Toward the Multicolor Limit
A thermodynamic design framework reveals how transfer‐printable TMD multijunction solar cells approach the multicolor limit. Within the 1.0–2.1 eV TMD bandgap window, a five‐junction ladder nears the efficiency plateau, while radiative efficiency, luminescent coupling, excitonic absorption, and bottom‐cell stability set the practical headroom for van ...

A novel noncontact method based on weak value amplification enables high‐sensitivity stress mapping of femtosecond laser processed silicon photonic chip substrates. It converts microscale stress into the birefringent phase via the photoelastic effect and reads it out with weak measurement, achieving a 0.37‐kPa detection limit.
