Abstract
We report on a technique for determining the change in the refractive index of photosensitive glass. We have demonstrated our interferometer-based technique on fiber preform and bulk glass samples, achieving an optical: path-difference (OPD) repeatability of 0.2 nm. For the bulk glass sample we measured an OPD of 15.2 ± 3.0 nm, corresponding to an index change of 2.1 ± 0.7 x 10-5 Our technique was found to he insensitive to the effects of photodarkening and material compaction.Citation
