Abstract :
We present the results of an experimental study of dynamic amplitude and phase Bragg gratings induced in a heavy-doped erbium fiber at the wavelengths 1532 and 1538 nm under the 980-nm pumping. The technique of two phase-modulated beams´ coupling was applied for an experimental measurement of the changes in refractive index and gain accompanying the gratings´ formation in the fiber, and an analysis based on the Kramers–Kronig Relations for the fiber absorption/gain spectra and two-pass amplifying was performed for modeling these changes.
