Description/Abstract
Over the past five years, a colour-centre model for the dynamics of the absorption induced in germanosilicate fibres upon exposure to blue/green light has been under development at Southampton. This model is introduced and its predictions used for the first time to test our proposed Kramers-Kronig mechanism for the concurrent refractive index changes induced in the visible and the infra-red. It is found that the predicted colour-centre population changes in the UV are to explain these refractive index changes. A possible alternative model, based on density changes in the glass triggered by colour-centre formation, is assessed experimentally and analytically. The implications of this result to photonically driven self-organisation in fibres is briefly assessed, and reference made to recent experimental results.
