title = "Effects of pre-strain on the intrinsic pressure sensitivity of polymer optical fiber Bragg-gratings",
abstract = "We experimentally demonstrate a scheme for improving the intrinsic pressure sensitivity of fiber Bragg-gratings (FBGs) inscribed in polymer optical fibers by applying pre-strain in order to suppress the pressure induced mechanical contraction of the fiber. This contraction would otherwise contribute to a blueshift of the Brag-wavelength, counteracting the dominant redshift caused by the stress-optic effect, which effectively reduces the pressure sensitivity of the FBG. By applying this technique we are able to improve the sensitivity of the FBG from 2.8 pm/bar to 7.3 pm/bar. {\textcopyright} (2017) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
