Paper Abstract
We experimentally demonstrate a novel fiber-optic pressure and temperature sensor using dual-FBG written in grapefruit
microstructured fiber (GMF) and standard single-mode fiber (SMF). The pressure sensitivity of FBG in GMF is much
larger than that of SMF because the large air holes in the cross section of GMF make it experience larger axial strain than
SMF in the presence of hydrostatic pressure. While the temperature responses of the two FBGs are almost the same due
to the similar material composition in the fiber cores. Hence, pressure and temperature can be simultaneously
determined.
