Chapter 2 : Fiber Bragg Gratings



The main principles of optical fibers and fiber Bragg gratings (FBG) are described in this chapter. The FBG fabrication and optical fiber photosensitivity characterization are also discussed. Finally, the characterization methods for FBGs and the gratings sensitivity to temperature and strain are presented.
