    Abstract: In a distributed Raman amplification system, the pump laser and the fiber are chosen so as to have characteristics which result in broadening of the DRBS. For example, with a transmission fiber through which signal light of a wavelength lambds propagates, and having zero dispersion at a wavelength lambdo; a pump laser producing counterpropagating pump light at a wavelength lambdp; where lambdp and lambds are on opposite sides of the zero dispersion wavelength is used. The transmission fiber may be large effective area fiber. In a Raman amplification system suitable for use in a WDM optical fiber communication system, pump lasers having mode spacing which is less than the optical bandwidth of the signal channel have been found to be advantageous.

    Abstract: A system and method for amplifying an optical signal within an optical waveguide amplifier including providing at least one optical waveguide amplifier having an input for receiving an optical source signal therein and an output, wherein a forward pumping direction extends from the input to the output and rearward pumping direction extends from the output to the input. The system also includes providing at least one excitation light source in optical communication with the optical waveguide amplifier and capable of generating at least one excitation light. The system further includes amplifying the source signal by pumping a first excitation light from the excitation light source in the rearward pumping direction, and amplifying the source signal by simultaneously pumping a second excitation light from the excitation light source in the forward direction.
