Advanced Optical Materials, EarlyView.New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.

Unidirectional Focusing of Light Using Structured Diffractive Surfaces
Advanced Optical Materials, EarlyView.This study presents a reciprocal diffractive unidirectional focusing design based on linear and isotropic layers. A set of cascaded diffractive layers is designed using deep learning to achieve efficient forward light focusing while suppressing backward propagation across various illumination angles.

Selective Directional Enhancement in Gold/Perovskite Quantum Dot Metasurfaces
Advanced Optical Materials, EarlyView.A thin gold layer can selectively enhance the directional radiation of a perovskite quantum dot (QD)1D metasurface by incorporating hybrid plasmonic excitation and redistributing diffraction orders from substrate to cover. The use of template‐assisted self‐assembly techniques enables breakthrough tunability in radiative properties over large areas ...
