Paper Abstract

The main goal of this paper is not to explain all experimental features observed in connection with UV-written refractive index gratings in silica glass-based fibers, but it is an attempt to present some ideas and possible way of thinking to help researchers in their work. We would like also to show usefulness and facilities of quantum chemical calculations in understanding of microstructure of silica glass, its point defects and processes initiated by UV laser irradiation. We show that the oxygen vacancy relaxation to the puckered state can explain several features of the UV- induced refractive index change in doped silica glass.
