Design and analysis of single-layer f-θ metalens enabling wide-field-of-view, low-distortion scanning

F-θ scanning lenses represent a critical component in laser systems for high-end intelligent manufacturing and optoelectronic applications, as they directly govern the system’s positioning accuracy, imaging resolution, and processing quality. In this work, we propose an ultra-thi...

Ultralow‐Noise Blue‐Green‐Light CsPbBr 3 Photodetectors Enabled by CuSCN Selective Coverage Toward Long‐Distance Underwater Wireless Optical Communication

ABSTRACT The excellent thermal stability and blue‐green spectral response window of all‐inorganic CsPbBr 3 perovskite make it highly suitable for underwater wireless optical communication (UWOC). However, in complex ocean environments, severe optical attenuation limits long‐dista...
