Photosensitivity as it relates with glass macroproperties

Abstract

Since Pelouze [1], it has been proposed that photosensitivity is a glass composition interacted property. Recent developments in Bragg grating technology have confirmed this analysis and indicated the importance of glass composition to improve glass photosensitivity as well as to measure the strength of the grating produced. Other important fact is the occurrence of high temperatures during the process of writing Bragg gratings which is usually mentioned in the literature.
