I. Joindot et F. Dupre, SPECTRAL HOLE-BURNING IN SILICA-BASED AND IN FLUORIDE-BASED OPTICAL-FIBER AMPLIFIERS, Electronics Letters, 33(14), 1997, pp. 1239-1240
The results of spectral hole burning measurements in silica-based and
in fluoride-based erbium-doped optical fibre amplifiers are compared.
In silica-based fibre the spectral hole appears clearly, while in fluo
ride-based fibre, the shape is different and weaker effects occur arou
nd the saturating wavelength.
