Abstract :
We present a physically meaningful semianalytic gain-clamping algorithm for multipump Raman fiber amplifier in large signal regime. By utilizing parameters from the steady state conditions, the suppression of gain excursion below 0.5 dB (up to 78/80 channel drop) can be achieved within microsecond/millisecond time scale, depending on the signal power level.
