Abstract.
A Ge-doped Raman fiber amplifier with enhanced signal-to-noise ratio is numerically analyzed using second Stokes control pulses. Inter-pulse noise power in the signal to be amplified is moved to the second Stokes pulse and therefore the signal-to-noise ratio for the amplified signal pulse is enhanced. The effects of different kinds of second Stokes pulse on the signal are reported.
