Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

Advanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

Double Bouligand Printed Twisted Stacks: Mirrored Chiroptical Polarization and Enhanced Compressive Mechanics

Advanced Optical Materials, EarlyView.
This work demonstrates the production of nature‐inspired double Bouligand structures via shear‐aligning cellulose nanocrystals for comparison against more commonly studied single Bouligand architecture. Optical and mechanical analysis shows retained chiroptical polarization and increased mechanical integrity under compression elucidated with ...

Tailoring Optical and Vibrational Properties by Bond Confinement: The Case of Metavalent Chalcogenide and Pnictogen Thin Films

Advanced Optical Materials, EarlyView.
This perspective explores how intrinsic confinement effects in metavalent chalcogenide and pnictogen thin films alter optical and vibrational properties. By comparing thickness‐dependent effects across prototypical systems, this work highlights the role of unconventional bonding in shaping coherent phonon dynamics and dielectric functions, offering new

Chiral Metasurfaces with Multidimensional Tunability for Optical Chiral States

Advanced Optical Materials, EarlyView.
A novel bilayer perovskite chiral metasurface enables tunable transitions between BIC‐associated vortex centres and circularly polarized states via rotational symmetry control. Breaking rotational symmetry and applying in situ rotation to the upper layer allows precise, omnidirectional tuning of C points in momentum space. This evolution forms a Möbius‐
