“…Plasma-induced modulational instability -After the very initial SPM stage (described above) is over, the interplay between nonlinear and dispersive effects can lead to an instability that modulates the temporal profile of the pulse, creating new spectral sidebands referred to as modulational instability (MI) in Refs. [15][16][17]). For instance, during the propagation of a continuous wave (CW) signal in an anomalously dispersive Kerr medium, perturbations in the amplitude of the carrier wave can trigger the generation of spectral sidebands, leading to the eventual break-up of the CW signal into a train of pulses [12,15,16].…”
