Tiny infrared chip could improve detection of gases and heat

MIT researchers have developed a chip-based optical device that dynamically controls infrared light using a tunable metasurface lens. Each microscopic pixel can independently switch between crystalline and amorphous states via a crossbar architecture borrowed from display technology, enabling pixel-level control of mid-infrared light without moving parts. The 6×6 pixel prototype was fabricated using conventional semiconductor manufacturing processes, suggesting scalability to millions of pixels. Potential applications include compact thermal imaging, chemical and gas detection, pollution monitoring, and optical neural network computing.
