Comparison of the decay behaviour of negative and positive index change fibre Bragg gratings
IEE Colloquium on Optical Fibre Gratings (Digest No. 1997/037).

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.
