Advanced Science, EarlyView.A gentle internal corrugation layer conformally reshapes the microcavity OLED stack, redistributing confined optical power toward extractable channels while preserving cavity‐controlled emission. Combined with optical clear resin and a resonance‐matched narrowband pTSF emissive system, this cavity‐compatible architecture delivers an external quantum ...

Advanced Science, EarlyView.Inspired by the twin grain boundary discovered in natural gyroidal networks, a series of gyroid‐derived photonic crystals are constructed based on defect‐symmetry engineering. The new series of structures enables monotonic tuning of the width of the photonic bandgap (PBG) while the central frequency of the PBG maintains stable.

Advanced Science, EarlyView.A partial‐inner‐cladding optical fiber (PICOF) is developed to suppress photothermal artifacts in fluorescent fiber‐optic thermometry by isolating the sensing layer from regions prone to photothermal effects. This structural design strategy enables high‐fidelity operation at elevated excitation power, achieving high accuracy (maximum absolute error ...

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.

Targeted Mechanogenetics to Modulate Specific Deep Neural Circuits
Advanced Science, EarlyView.This study introduces mechanogenetics, a nanobubble‐enhanced sonogenetic strategy for selective modulation of feeding‐related neural circuits in the mouse lateral hypothalamus. Mechanogenetic stimulation modulates feeding behavior through glutamatergic projections from the lateral hypothalamus to the ventral tegmental area, highlighting its potential ...
