A method for controlling the shape and magnitude of the L-band gain spectrum of an erbium doped optical amplifier, in one aspect, involves saturating the amplifier gain with a saturating signal in the L-band. Another aspect of the method involves saturating the amplifier gain by controlling the temperature of the gain medium. By pumping the amplifier in the 980 nm and/or the 1480 nm pump bands, the gain spectra at different inversion levels are adjusted.
L'invention concerne un procédé de réglage de la forme et de l'intensité du spectre de gain de la bande L d'un amplificateur optique dopé à l'erbium, consistant d'une part à saturer le gain de l'amplificateur à l'aide d'un signal de saturation dans la bande L. Le procédé consiste, d'autre part, à saturer le gain de l'amplificateur par réglage de la température du milieu de gain. Les spectres de gain à différents niveaux d'inversion sont réglés par pompage de l'amplificateur dans les bandes de pompage de 980 nm et/ou de 1480 nm.
