Modulation Instability (MI) is a nonlinear instable phenomenon arising in dispersive fiber optics under proper conditions. When a strong pump CW is injected a perturbation, initially negligible, undergoes amplification. In this paper we derive the instable regime theoretical conditions focusing on the pump depletion. This step is neglected in most of(More)
