Kovacs-like memory effect mediated fiber Bragg grating: resembling a silica quipu

Nature Communications
In antiquity, civilizations employed stone carvings and knotted quipu cords for information preservation. Modern telecommunications rely on optical fibers - silica glass strands engineered for light transmission - yet their capacity as archival media ...

Strong Plasmon–Exciton Coupling Tuned by Corner Etching of Gold Nanocubes and Nanotriangles

Advanced Optical Materials, EarlyView.
Systematic etching of gold nanocubes (AuNCs) and nanotriangles (AuNTs) reveals how nanoparticle morphology governs plasmon–exciton strong coupling. While rounding the corners of AuNCs weakens their coupling, triangular geometries robustly preserve deep strong coupling.

Design and numerical analysis of a gap-compensated low loss hollow-core antiresonant fiber with nested elliptical tubes

Scientific Reports
In this research, we propose a novel hollow-core anti-resonant fiber structure designed to enhance light confinement and reduce losses. Our simulation results indicate that the LP01 mode loss is reduced to 1.807 × 10⁻⁶ dB/km at a wavelength of 1.52 μm ...

Degradation of Blue MR‐TADF OLEDs: Host‐dependent Effects of mCBP and MADN Revealed by Fragmentation Profiling

Advanced Optical Materials, EarlyView.
Degradation in blue MR‐TADF OLEDs originates from high triplet density caused by slow RISC. LDI‐TOF MS directly detects host‐ and emitter‐derived fragments, providing molecular insight into how triplet accumulation drives degradation in the emissive layer. ABSTRACT Blue organic light‐emitting diodes (OLEDs) employing multi‐resonance thermally activated

Chameleonic Color‐Variable Microbead Emitters for Multilevel Spectroscopic Encryption from Visible to Infrared Wavelengths

Advanced Optical Materials, EarlyView.
Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,
