Abstract

A lot of experiments have been performed to measure the stability of Bragg gratings in silica based optical fibers for various temperatures. The most famous one is from Erdogan et al. [6, 7] who show a law like $\frac{1}{1+a{t}^{\alpha }}$ with α increasing on the temperature. Applying this mathematical function systematically, various authors have found other variations. Furthermore, some stability measurements have been made according the writing conditions and in some glasses this has been found mutually dependent [1, 2].
