Phase and power experimental study of seeded modulation instability in passive fiber ring cavities

Modulation instability (MI) mechanism results from the interplay between dispersion, nonlinearity and detuning in passive fiber cavities. This process allows under specific conditions ruled by a phase matching relation to a weak perturbation to grow exponentially. Most investigations have been performed from self starting MI process initiated by noise and only a few focus on coherently seeded cavities [1]. Here, we study a cavity seeded by a strong pump surrounded by two symmetric side lobes (input seeds). We numerically demonstrate that under specific relative phase values between input seed waves and input pump the parametric gain experienced by weak perturbations can vanish. Preliminary experimental results to confirm these predictions are reported.
