CA 2405576

A novel circuit (Figure 1A) is disclosed for compensating for ASE in the gain control mode of an optical amplifier (10). The circuit (figure 1A) includes a gain medium (20), a pump source (22), an input port (24), an output port (26), two optical taps (28 and 30), a first detector (32), and a second detector (34). Fifure 1B further discloses a novel method for deriving a control signal from output of the two optical detectors.

L'invention concerne un nouveau circuit (figure 1A) qui permet d'assurer la compensation d'ASE en mode de réglage du gain d'un amplificateur optique. Le circuit (figure 1A) comprend un moyen (20) de gain, une source (22) de pompage, un port (24) d'entrée, un port (26) de sortie, deux branchements optiques (28 et 30), un premier détecteur (32) et un deuxième détecteur (34). La figure 1Bprésente en outre un nouveau procédé de dérivation d'un signal de commande à partir de la sortie des deux détecteurs optiques.
