Distributed Transverse Stress Sensor Based on Mode Coupling in Weakly-Coupled FMF
IEEE Photonics Journal, 2022 Distributed optical fiber sensors (DOFSs) have faced the challenge of measuring transverse stress along the fiber and the current main approach has been based on polarization coupling effect in polarization-maintaining fibers (PMFs), which has short ...

Invited paper: Characterization of few mode fibers and devices [PDF]
Optical Fiber Technology, 2019 Abstract This paper reviews characterization techniques for few mode fibers and components. The focus is on interferometric techniques including spatial and spectral resolved imaging (S2). Simple interferometric measurements are shown to be able to give quite comprehensive information including measurement of relative group delay.

Optics ExpressWe report a systematic investigation on the mode-resolved nonlinear absorption characteristics of the few-mode fiber-multimode fiber-few-mode fiber (FMF) structure. Firstly, the transmission formulas of the FMF structure are derived, demonstrating that the transmission is mode-dependent.

Few-mode fiber based optical sensors
Optics Express, 2015 Few-mode fibers (FMFs) have found applications in optical communications and sensors with attractive features that standard single mode fiber (SSMF) do not possess. We report our recent progress on FMF based optical sensors, and show the potential of utilizing the spatial dimension for multi-parameter sensing with discrimination capability.
