Photoluminescence properties of point defects in Ge-doped fibers and preforms

2008

International audience; The optical properties of Ge-related point defects are often the most important parameter for the performances of silica based optical fibers. On one side their presence is often detrimental for the light transmission, on the other side some defect typologies exhibit modifications under radiation exposure thus offering the peculiar property of photosensitivity that is exploited to build technologically relevant devices such as fiber Bragg gratings.

Radiation Effects on Silica-Based Preforms and Optical Fibers - I: Experimental Study with Canonical Samples

2008

International audience; The influence of the F- and Ge-doping on the fiber radiation responses is investigated through online measurements of the UV-visible induced attenuation and spectroscopic studies (ESR, confocal microscopy of luminescence) on prototype samples
