Thermal stability of photosensitive Bragg gratings in sputter-deposited germanosilicate glass

The thermal stability of photo-imprinted Bragg gratings formed in reactive-atmosphere, RF-magnetron sputtered germanosilicate thin films was evaluated in terms of point defect modifications observed during isochronal annealing. Optical and magnetic spectroscopies were utilized to evaluate structural...
