Abstract :
This article presents the fabrication of Long Period Gratings in Optical Fiber (LPFGs) applied to the sensing loops. In implementing the manufacturing method used a commercial splicer fiber optic (FiTel S-175), capable of being programmed to a short section of standard optical fiber (SMF28) is taken at intervals between shots in a range from 400μm to of 650μm. The LPFGs Being able to obtain through attenuation bands above 20 dB, while the wavelength of central attenuation is close to 1550nm. We shows the experimental scheme to measure curvatures with diameters ranging between 12 and 13.1cm, having a linear variation of peak output cut at the LPFGs with tuning of 17nm.
