Modulation instability, Cherenkov radiation, and Fermi–Pasta–Ulam recurrence

Soto-Crespo, Jose M.; Ankiewicz, Adrian; Devine, Natasha; Akhmediev, Nail


We study, numerically, the influence of third-order dispersion (TOD) on modulation instability (MI) in optical fibers described by the extended nonlinear Schrödinger equation. We consider two MI scenarios. One starts with a continuous wave (CW) with a small amount of white noise, while the second one starts with a CW with a small harmonic perturbation at the highest value of the growth rate. In each case, the MI spectra show an additional spectral feature that is caused by Cherenkov radiation....[Show more]
