Research on Thermal Stability of Fiber Bragg Gratings
The principle on refractive index of core and reflectivity of FBG changing with temperature and time was analyzed. With some research work on appropriate model, the concept of accelerating decay is raised, upon which a novel annealing process is established. With the data measured, the future characteristic of grating can be given under certain temperature and time. The theoretical and practical results are almost in agreement.
