In-Sensor Visible and Mid-Infrared Dual-Band Perception and Computing

Abstract Machine vision in complex environments requires hardware that can integrate multispectral sensing with real-time front-end information processing. Visible light (VIS) and mid-infrared (MIR) signals provide complementary scene information, yet existing photodetectors cann...

Plasmonic-enhanced lanthanide nanotransducers for mid-infrared detection

Advanced mid-infrared (MIR) detection underpins a wide range of applications from chemical sensing to thermal imaging. Conventional MIR photodetectors rely on narrow-bandgap semiconductors that typically require cryogenic cooling, whereas uncooled alternatives suffer from inheren...
