description: The main objective of this thesis was to investigate how it is possible to extend the master curveapproach to complex components, in order to calculate annealing conditions and giving a life timeprediction according those annealing conditions. We studied the stability of a simple Bragg grating (noapodisation, constant pitch, no tilt). Then, we have been able to study the problem of the stability(according to specific criteria) of complex components: CDC and GFF monofilters. This thesis allowed toshow precisely what is the VAREPA framework and how to apply it to optical telecommunicationsproblems. To give an answer to the question of the possibility of extending the master curve approach tocomplex components, series of accelerate aging studies have been carried out. For this purpose, ameasurement protocol including the determination of the measurement uncertainty was developed. Thisprotocol allow, to determine confidence intervals on the life time prediction.We studied the kinetics of photo induced index growth in the optical fiber dedicated forfabrication of CDC (Coreactive). This study allowed us to demonstrate that the predominant reaction atthe origin of changes in refractive index is activated by a one photon absorption. On the other hand wehave extended the VEREPA framework used to predict the Bragg gratings erasure to take into account thegrowing kinetics. In a second step we tried to calculate annealing conditions in the presence of residualmolecular hydrogen and associated Bragg grating life time prediction. For that purpose we established themaster curve of photo-induced Bragg gratings without annealing, then we validated the annealingconditions and lifetime predictions by building a new master curve from aging of annealed Bragg gratings(in presence of residual hydrogen).We studied the thermal stability of hydrogenated fiber Bragg gratings dedicated to futuremonofiltres GFF in similar conditions to those components. We used master curves from basic Bragggra…
