A Novel Approach to Fabricate High-Temperature Resistant Fiber Bragg Gratings

Abstract

Ever since the discovery of photosensitivity in optical fibers by Hill er al. in 1978 [1] and the development of the transverse holographic writing technique by Meltzef al. in 1989 [2] there has been increasing interest in developing gratings with increased temperature stability. The decay of fiber Bragg gratings has been shown to depend on the fabrication process [3,4], the doping [3,5], and the temperature history [6].
