Chip‐Integrated Gas Sensors with Tunable Diode Laser Absorption Spectroscopy (Adv. Mater. Technol. 7/2026)

Chip-Integrated Gas Sensors The cover highlights cutting-edge advancements in chip-integrated TDLAS gas sensors, including waveguide designs, fabrication techniques, and spectral algorithms. Five sensing-waveguide configurations are central to the design, with the background illustrating sensing algorithms. The output signal at the bottom shows a typical wavelength-modulation signal. These emphasize the coordinated evolution of spectral techniques, photonic devices, and intelligent algorithms in the TDLAS field. More detail can be found in the Review by Zunyue Zhang, Jiaqi Wang, Tiegen Liu, Zhenzhou Cheng, and co-workers (10.1002/admt.202501609).
