Abstract

It is possible to predict more accurately the laser fiber refractive index when we apply a stress induced index change model together with the measured preform index profile data. The improved fiber index difference estimates enable to fine tune the deposition process so that the index difference values of the drawn fibers will be close to the designed values.
