Abstract :
This paper presents the gain performance of fiber Raman gain amplifier using multiple pump wavelength sources based on the triangular index profile of the inner core of our designed fiber. This profile turns out to be the best in our earlier report based on single pump. We show the achievement of flat gain bandwidth with proper choice of fiber parameters and the pump wavelengths.
