Abstract
The multi-channel fiber amplification system and associated method includes a fiber amplifier which solves problems with power poaching by simultaneously amplifying a pair of optical signals in a similar manner even if the fiber amplifier is saturated. The fiber amplifier, has greater absorption than emission for wavelengths immediately less than a reference wavelength and greater emission than absorption for wavelengths immediately greater than the reference wavelength. The multi-channel fiber amplification system also includes a pump source having a Stokes band which includes at least some wavelengths greater than the reference wavelength of the fiber amplifier. The multi-channel fiber amplification system further includes first and second signal sources for providing first and second signals, respectively, having first and second wavelengths, respectively. The first and second wavelengths are both within the Stokes band of the pump source and are greater than the reference wavelength of the fiber amplifier such that the fiber amplifier simultaneously amplifies both the first and second signals by stimulated Raman scattering.
