UV-induced reaction of H2 with the core of germanosilicate and aluminosilicate fiber preforms

Dalle, C., Cordier, P., Depecker, C., Bernage, P., Douay, M., Niay, P., Bayon, J.F. and Dong, L. (1997) UV-induced reaction of H2 with the core of germanosilicate and aluminosilicate fiber preforms At Bragg Gratings: Poling and Photosensitivity (BGPP), United States. 26 - 28 Oct 1997.

Record type: Conference or Workshop Item (Paper)


The photosensitivity of glasses can be significantly enhanced by high- pressure low-temperature hydrogen loading prior to UV exposure. The chemical reactions that occur between hydrogen and glass under UV exposure are thus of primary importance for the understanding of the mechanisms of H2 photosensitivity enhancement. We have used infrared spectroscopy to characterize the microstructural modifications in Hz-loaded optical fiber preform cores exposed to UV laser light. Infrared spectroscopy in the 3µm range is very well adapted to such a characterization because it is highly sensitive to hydroxyl groups.
