Optomechanical sensor network with fiber Bragg gratings.

ABSTRACT: Sensor networks are indispensable for diverse engineering applications and cutting-edge scientific research. Recent advances in cavity optomechanics have enabled progress in ultrasensitive sensing. Crucially, the resonant enhancement of optical and mechanical responses enables highly sensitive detection of small perturbations, making it a promising candidate for next-generation ultrasensitive sensor networks. However, the intrinsic limitations of existing optomechanical sensors-such as fiber-optic integration and polarization-dependent response- have hindered progress in this field. Here, we demonstrate a kilometer-scale optomechanical sensor network, integrating multiple fiber-optic optomechanical sensors into a standard single-mode fiber. Leveraging commercially available fiber Bragg gra
