Paper Abstract

Pressure and temperature cross sensing restricted the application of bare fiber FBG , especially when FBG was used to measure low hydrostatic pressure. Side-hole package is practical to overcome pressure and temperature cross sensing and enhance FBG pressure sensitivity to measure hydrostatic pressure, but it aroused package stability problem that the FBG spectrum seemed distortion, which will brought measurement difficulties. Novel side-hole package was raised, with reasonable structure and mechanism, to improve the package stability and eliminate FBG distortion. The theoretical analysis presented the stress and deformation in fiber core within packages, and forecast the birefringence may be amplified in novel package according to the package structure, which will support the measurement based on polarization spectrum technique. The experiment result proved theoretical analysis and shown that the novel side-hole package provided stability support while kept the advantage of the former side-hole package.
