Modulational instability Instabilité modulationnelle
rdfs:comment
En optique non linéaire et en dynamique des fluides, l'instabilité de modulation ou instabilité modulationnelle est un effet de renforcement, par la non-linéarité, d'une déformation d'une onde périodique, menant à la génération de bandes de gain dans le spectre fréquentiel. Elle peut entraîner la rupture de l'onde en un train d'impulsions. In the fields of nonlinear optics and fluid dynamics, modulational instability or sideband instability is a phenomenon whereby deviations from a periodic waveform are reinforced by nonlinearity, leading to the generation of spectral-sidebands and the eventual breakup of the waveform into a train of pulses.

dbo:abstract
En optique non linéaire et en dynamique des fluides, l'instabilité de modulation ou instabilité modulationnelle est un effet de renforcement, par la non-linéarité, d'une déformation d'une onde périodique, menant à la génération de bandes de gain dans le spectre fréquentiel. Elle peut entraîner la rupture de l'onde en un train d'impulsions. Ce phénomène a été historiquement découvert et modélisé pour les ondes de gravité en eau profonde par T. Brooke Benjamin et Jim E. Feir en 1967. Il est par conséquent aussi connu sous le nom d' instabilité de Benjamin-Feir. C'est un mécanisme possible pour la génération de vagues scélérates. In the fields of nonlinear optics and fluid dynamics, modulational instability or sideband instability is a phenomenon whereby deviations from a periodic waveform are reinforced by nonlinearity, leading to the generation of spectral-sidebands and the eventual breakup of the waveform into a train of pulses. It is widely believed that the phenomenon was first discovered − and modeled − for periodic surface gravity waves (Stokes waves) on deep water by T. Brooke Benjamin and Jim E. Feir, in 1967. Therefore, it is also known as the Benjamin−Feir instability. However, spatial modulation instability of high-power lasers in organic solvents was observed by Russian scientists N. F. Piliptetskii and A. R. Rustamov in 1965, and the mathematical derivation of modulation instability was published by V. I. Bespalov and V. I. Talanov in 1966. Modulation instability is a possible mechanism for the generation of rogue waves.
