Advanced Optical Materials, EarlyView.Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

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.A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

Advanced Optical Materials, EarlyView.Colloidal lithography is a low‐cost, simple and scalable technique to fabricate correlated‐disorder nanostructures for light‐trapping in solar cells. This work investigates the control of polystyrene particle distribution in colloidal lithography, highlighting the importance of particle surface functionalization as well as the ability to tune the ...

Advanced Optical Materials, EarlyView.Here we use a template‐assisted self‐assembly approach of metal colloids onto metal films to produce hybrid plasmonic metasurfaces that integrate nanoparticle‐on‐mirror cavities with periodic metal colloid arrays. The resulting coupling between gap plasmons and grating‐coupled surface plasmon polaritons enables programmable hybrid modes with tailored ...

Photoluminescent Color Centers on a Mainstream Silicon Photonic Foundry Platform
Advanced Optical Materials, EarlyView.Silicon photonic chips route and process light efficiently but are inherently inefficient at generating it. Here, bright light‐emitting defects, W‐centers, are written into the silicon layer of finished chips from a mainstream commercial foundry: high‐energy ions are implanted straight through the protective oxide and activated by a 250∘C$^\circ{\rm C}$

Sub‐Diffraction and Irreversibly Tunable Imaging With Potato Starch Lenses
Advanced Optical Materials, EarlyView.Native potato starch granules function as sustainable birefringent microlenses that enable polarization‐controlled conventional and vortex lensing via spin‐to‐orbital angular momentum conversion. They provide sub‐diffraction and spiral‐contrast imaging, support vortex‐array generation with controllable topological‐charge sign, exhibit irreversible ...

Crossover From Excitonic to Bulk Emission in Metal Halide Perovskite Nanocomposites
Advanced Optical Materials, EarlyView.A transition from excitonic to free‐charge recombination is uncovered in perovskite nanocomposites as a function of nanostructure size using PLQY(R, F) mapping as a function of excitation fluence (F) and repetition rate (R). These findings demonstrate that PLQY(R, F) mapping serves as a powerful and non‐invasive tool to extract quantitative information
