Title (EN) SINGLE-BAND OPTICAL FIBER AMPLIFIER
(FR) AMPLIFICATEUR A FIBRE OPTIQUE MONOBANDE
Abstract: front page image
(EN)The invention relates to a single-band optical fiber amplifier (10) comprising an amplifying fiber (4) and pumping means (3) in addition to reverberating means (20, 11) that send back amplified spontaneous emission noise to the amplifying fiber. The invention makes it possible to limit losses that are due to amplified spontaneous emission noise by sending said noise back towards the amplifying fiber in a direction of propagation which is opposite to the direction of propagation of the signal that is to be amplified.
(FR)L'invention concerne un amplificateur à fibre optique monobande (10), comprenant une fibre amplificatrice (4) et des moyens de pompage (3) ainsi que des moyens de renvoi (20, 11) renvoyant le bruit d'émission spontanée amplifiée vers la fibre amplificatrice. L'invention permet de limiter les pertes dues au bruit d'émission spontanée amplifiée par renvoi du bruit d'émission spontanée amplifiée vers la fibre amplificatrice dans le sens de propagation opposé à celui du signal à amplifier.
