Abstract:
An amplification device includes an element for splitting an input optical signal into first and second optical signals having first and second polarization modes, first and second amplification stages each including polarized SOAs for amplifying the first and second optical signals depending on driving currents, an intermediate processing stage for compensating optical characteristics of the optical gain bandwidth of the first amplification stage depending on driving currents, an element for combining the first and second optical signals outputted by the second amplification stage to produce an output optical signal, and a control means 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 and on a targeted power of the output optical signal.

Claim (Index 6):
Amplification device according to  claim 1 , wherein said intermediate processing stage comprises a) a second combination element arranged for combining said first and second amplified optical signals outputted by said first amplification stage to produce an intermediate optical signal, b) a variable optical attenuator arranged for compensating, on said intermediate optical signal, a tilt of said optical gain bandwidth of said first stage, c) a gain flattening filter arranged for compensating, on said intermediate optical signal, ripples of said first amplification stage, and d) a second splitting element arranged for splitting said intermediate optical signal, processed by said variable optical attenuator and gain flattening filter, in said first and second optical signals having respectively said first and second polarization modes.
