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 ...

Helicity‐dependent all‐optical magnetization switching was demonstrated for the Bi‐ and Ga‐substituted rare‐earth (R) iron garnet crystal thin films (Bi,Ga:RIG; R = Eu3+, Nd3+, and Y3+). The efficiency followed the order EIG > NIG > YIG. These results show the correlation between 4f orbital moment (4f〈L〉) of R3+ and helicity‐dependent optical ...

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 ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Geometric approach based on optimal toric packings for photonic crystals and metamaterials design
We introduce new classes of nanostructures—optimal toric packings of particles and their Voronoi tessellations—that exhibit remarkable properties for photonic and potentially for plasmonic/phononic crystals design.

Hyperuniform Disorder in Photonic Crystal Slabs With Intrinsic Non‐Hermiticity
Light propagation in photonic crystal slabs with imposed hyperuniform disorder is investigated theoretically and numerically. The hyperuniform disorder is imposed by varying the hole size. The photonic crystal is intrinsically non‐Hermitian due to radiative loss, with non‐Hermiticity appearing as a complex effective mass of a quadratic photonic band ...

Rigid Boron‐Fused Frameworks for Efficient Near‐Infrared Emission and Optical Gain Beyond 900 nm
Multiple‐resonance (MR)‐derived boron‐fused frameworks were integrated into narrow‐gap, long‐range charge‐transfer emitters to reduce structural relaxation and electron‐vibrational coupling. This strategy significantly decreases nonradiative losses, leading to improved near‐infrared (NIR) luminescence efficiency and low‐threshold amplified spontaneous ...
