Room-Temperature Mid-Infrared Detection Using Metasurface-Absorber-Integrated Phononic Crystal Oscillator (Laser Photonics Rev. 19(20)/2025)

Abstract

Phononic Crystal Mid-IR Detector

The cover shows a false-colored SEM image of a phononic-crystal-oscillator-based mid-infrared detector. The high-Q phononic crystal resonator achieves ultralow readout noise, resulting in highly sensitive, wide dynamic range mid-IR detection. The metasurface absorber array enables wavelength and polarization selective mid-infrared detection. For more details, see Research Article e00498 by Yu Yao, Linbo Shao and co-workers.
