ABSTRACT:
A nonlinear polarization amplifier stage includes a gain medium operable to receive a multiple wavelength optical signal. The amplifier further includes a pump assembly operable to generate a plurality of pump wavelengths forming a pump spectrum comprising a plurality of peaks. The amplifier also includes a coupler operable to introduce the at least one of the plurality of pump wavelengths to the gain medium to facilitate amplification of at least a portion of the multiple wavelength optical signal through nonlinear polarization. In one particular example, at least a wavelength or an intensity of the at least one of the plurality of pump wavelengths is manipulated to affect the shape of a gain curve associated with the multiple wavelength optical signal in the amplifier stage.
