Abstract
A germanosilicate glass graded-index fibre preform thin sample was submitted to a wide range of 266 nm excitation powers across its core. The resulting 400 nm luminescence signal was found to follow the index profile of the preform at low excitation power and to be bleached at higher power above a certain Ge-concentration threshold. This threshold changed to lower Ge-concentration values with higher excitation power
