We propose a simple technique to optimize a multi-wavelength backward-pumped fiber Raman amplifier. Based on the geometric characteristics of Raman gain profile, we approximate it using several straight lines and utilize slope compensation technique to achieve flat and wideband gain profile. Good simulation results are obtained.
