Comparison of the decay behaviour of negative and positive index chance fibre Bragg gratings

W.F.Liu, L.Dong, L.Reekie, D.N.Payne

Abstract

We have studied the thermal stability of both negative and positive index gratings produced by a 193nm excimer laser. A complex decay process has been observed in gratings consisting of both types of index change. This phenomenon can be explained by our recently proposed three energy level model.
