The alteration of the bandwidth of an optical amplifier. Before alteration, optical signals having a first set of wave-lengths are provided through a gain medium of the optical amplifier. In addition, a first pump having a set of pump wavelengths is propagated through the gain medium to thereby amplify the optical signals. After alteration, optical signals having at least a partially different set of wavelengths are able to be optically amplified by coupling a second pump into the optical medium. The second pump is at least partially distinct from the first pump in that the second pump includes at least one pump wavelength that was not included in the first pump.

l'objet de cette invention est la modification de la largeur de bande d'un amplificateur optique. Avant modification, des signaux optiques affectées d'une premier ensemble de longueurs d'onde sont via un milieu actif de l'amplificateur optique. De plus, une première pompe dotée d'un ensemble de longueurs d'onde est propagée à travers le milieu actif, ce qui amplifie les signaux optiques. Après modification, des signaux optiques affectées d'un ensemble au moins partiellement différent de longueurs d'onde peuvent être amplifiés optiquement par couplage d'une seconde pompe dans le milieu optique. La seconde pompe est au moins partiellement distincte de la première pompe dans la mesure où elle comprend au moins une longueur d'onde de pompe qui n'était pas incluse dans la première pompe.
