Abstract
Recent investigations have shown that the self- Raman interaction in optical fibers causes pulses to shift In frequency as they propagate.1–3 The combination of the Kerr nonlinearity and stimulated Raman scattering produces ultrashort pulses, a process known as soliton-Raman pulse generation.4 These pulses, however, copropagate with the pump over many kilometers without an accompanying shift in frequency. We present both experimental and theoretical results to explain this discrepancy. We show that the presence of the pump wave is responsible for the suppression of the self-frequency shift by including an extra term in the nonlinear Schrodinger equation to account for the frequency-dependent gain of the pump wave.
