Abstract:
A method for regenerating optical signals includes determining an input including a source amplitude-modulated optical signal, regenerating the source amplitude-modulated optical signal by using successive saturation modes of amplification, and producing an output optical signal from the regeneration. The source amplitude-modulated optical signal includes input power modulation levels that each indicate information carried on the source amplitude-modulated optical signal. The output optical signal includes output power modulation levels that include information equivalent to information of the input power modulation levels.
