Abstract

Spectral broadening due to Modulation Instability (MI) during nonlinear propagation in fiber optics, can arise from noise amplification and involve incoherent and complex coupled processes, making their experimental control challenging. Over the years, MI control within both noise-driven and seeded regimes demonstrated different degrees of success [4]. The corresponding spectral correlation maps can be extracted, as seen in Fig. 1(c-d), and the correlation between two selected wavelengths ρ(λ_a, λ_b) can be optimized by iteratively adjusting the wavelength and phase of the input seeds, as shown in Fig. 1(b).
