A High-Temperature Fiber Sensor Using a Low Cost Interrogation Scheme
Sensors, 2013 Regenerated Fibre Bragg Gratings have the potential for high-temperature monitoring. In this paper, the inscription of Fibre Bragg Gratings (FBGs) and the later regeneration process to obtain Regenerated Fiber Bragg Gratings (RFBGs) in high-birefringence

Uniaxial Strain‐Driven Ferroelastic Domain Tuning in LaAlO3${\rm LaAlO}_3$
Advanced Science, EarlyView.The present work demonstrates based on AFM, μ$\umu$‐Raman spectroscopy, XRD, and first‐principles, that uniaxial strain provides a handle for tuning the ferroelastic domain populations in lanthanum aluminate, driving a continuous and controlled phase transition from a four‐variant rhombohedral crystal system to a two‐variant orthorhombic crystal system

Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films
Advanced Science, EarlyView.The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.

Mechanically‐Gated Stochastic Resonance for All‐Optical Acoustic Sensing in Noisy Environments
Advanced Science, EarlyView.A mechanically‐gated stochastic resonance (MGSR) sensing system is demonstrated, wherein stochastic resonance is enabled by an all‐optical bistable fiber Bragg grating feedback loop and gated by mechanical resonance. Under ambient noise, the system generates bistable outputs satisfying the Kramers escape‐rate condition, yielding signal‐to‐noise ratio ...

Hierarchical Organization of Biomaterials in the Formation of Photonic Nanostructures
Advanced Science, EarlyView.Natural organisms create vibrant structural colors through precisely organized nanostructures formed under mild biological conditions. This review explores how cellulose, chitin, corneous beta‐protein, and melanin form complex nanostructures across molecular, mesoscale, and tissue levels.

Advanced Science, EarlyView.Cobalt is incorporated more readily into garnet Li6.6La3Zr1.6Ta0.4O12 when sintered in argon than in air. Under argon, Co in the garnet lattice lowers the total conductivity three‐ to fourfold; in air, Co segregates as LiCoO2 and raises the electronic conductivity about 100‐fold instead.
