## Abstract A fiberβloop ringβdown spectroscopy based on multimode fiber is proposed for pressure measurement. It has been found that the multimode fiberβloop ringβdown pressure sensor has higher sensitivity and larger dynamic range up to 6.2 Γ 10^7^ Pa compared to the single mode counterpart. Good
We report on sensitivity control of fiber optic sensors using microbend long-period fiber gratings. By tuning the phase difference between a pair of periodically aligned rod arrays that sandwiches a single-mode fiber, we can change the coupling strength of the core mode with radiating cladding modes
