Fig. 1: Illustration of incoherent modulation instability dynamics.
From: Deep learning prediction of noise-driven nonlinear instabilities in fibre optics
a Spontaneous modulation instability dynamics: Spectro-temporal evolution of noisy input pulse (29.1 ps) propagating nonlinearly in an optical fibre, obtained via numerical simulations. b Seeded modulation instability dynamics: Spectro-temporal evolution of the same noisy input pulse copropagating with two weak but coherent optical seeds temporally superimposed with the pump. In both cases, the averaged input and output intensity profiles are shown with thick blue and red lines, respectively. The results of different noisy realizations are shown with dashed grey lines while the intensity profiles of the selected case (displayed in the evolution plot) are shown with a black line.
