Advanced Materials Technologies, EarlyView.This study demonstrates short, length‐independent group delay supported by topological edge states in open Su–Schrieffer–Heeger networks. Strong boundary port coupling enables an order‐of‐magnitude latency reduction compared to bulk modes, alongside robust protection against bulk disorder.

Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes
Advanced Optical Materials, EarlyView.We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...

Advanced Optical Materials, EarlyView.Metallic dimer antennas on top of the phase‐change material Ge3Sb2Te6 are addressed with laser pulses, resulting in inhomogeneous crystallization. A self‐consistent multiphysics model is employed to simulate the crystallization and to understand the resulting shift of the antenna resonance.

Linear and Nonlinear Optical Tuning With Sb2S3‐Based Metasurfaces
Advanced Optical Materials, EarlyView.Sb2S3${\rm Sb}_2{\rm S}_3$ resonant metasurfaces provide large, reconfigurable optical modulation and tunable enhanced nonlinear emission across telecommunication wavelengths. Monolithic structures achieve 92% transmission modulation and 150 nm resonance tuning, while hybridization with silicon enables strong modulation at nearly half the switching ...
