Abstract
A novel hydrostatic pressure sensor based on a few mode fiber (FMF) is proposed. The FMF-based hydrostatic pressure sensor is simply formed by splicing a segment of FMF to two segments of single mode fibers, where the FMF is used as the sensing element. The mode interference between LP01mode and LP11mode of the FMF provides an interference spectrum of the FMF-based hydrostatic pressure sensor which is sensitive to the hydrostatic pressure applied on the FMF. We experimentally show that there is a linear relationship between the hydrostatic pressure and the wavelength shift of the interference spectrum of the FMF-based hydrostatic pressure sensor.
