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 ...

Scalable Design and Optimization of Reconfigurable Sb2S3 Metasurfaces
Advanced Optical Materials, EarlyView.Scalable optimization methodologies are developed for reconfigurable Sb2S3 Huygens metasurfaces by combining localized phase‐match and overlap‐integral cost functions that account for inter‐element coupling. The framework enables computationally efficient design of large‐area, dual‐state flat optical devices with arbitrary wavefront transformations ...
