Abstract

An amplification device (1) comprises: - an element (2) for splitting an input optical signal in first and second optical signals having first and second polarization modes, -first (3 1 ) and second (3 2 ) amplification stages each comprising polarized SOAs for amplifying the first and second optical signals depending on driving currents, - an intermediate processing stage (4) for compensating optical characteristics of the optical gain bandwidth of the first amplification stage (3 1 ) depending on driving currents, - an element (5) for combining the first and second optical signals outputted by the second amplification stage (3 2 ) to produce an output optical signal, and - a control means (6) producing the driving currents depending on information representative of powers of the first and second optical signals before the polarized SOAs of each amplification stage (3 1 -3 2 ) and on a targeted power of the output optical signal.
