The integration of conventional silica optical fibers with optoelectronic materials and electrical structures opens the door to miniaturized and multifunctional all-fiber optoelectronic systems wit…
A microfiber Bragg grating (MFBG) bonded using tapered cantilever was designed to improve ultrasonic sensitivity, and was investigated using experimental, theoretical, and numerical methods. The ul…
As the most common member of the underground pipeline, optical cable has already spread throughout the urban region. By combining the distributed acoustic sensing (DAS) system with the existing opt…
Optical interferometric sensors have been widely used for highly sensitive detection of various physical quantities, and most of them operate in simple intensity interrogation mode. The deviation b…
Automated machine learning (AutoML) has achieved remarkable progress on various tasks, which is attributed to its minimal involvement of manual feature and model designs. However, most of existing …
We demonstrate a fiber magnetic field sensor based on multimode fiber specklegrams. The magnetic field is detected by measuring the change of speckle patterns with digital correlation technology. W…
