Self-phase modulation (original) (raw)
Selbstphasenmodulation (SPM) (engl.: self phase modulation) ist ein nichtlinearer optischer Effekt, der bei Wechselwirkung von elektromagnetischer Strahlung mit Materie auftritt. Die Strahlung wird spektral symmetrisch um neue Frequenzkomponenten erweitert.

(de) L'automodulation de phase (self-phase modulation, souvent abrégé en SPM en anglais) est un effet optique non linéaire d'interaction lumière-matière (gaz, solide, liquide). Une impulsion ultra-courte, lorsqu'elle voyage dans un milieu matériel, induit une variation de l'indice de réfraction de ce milieu par effet Kerr. Cette variation induit à son tour un décalage de phase dans l'impulsion, ce qui conduit à une modification du spectre en fréquence de l'impulsion. L'automodulation de phase est un effet important dans les systèmes optiques qui utilisent des impulsions brèves et intenses, tels que les lasers et les réseaux de communications par fibre optique. (fr) Self-phase modulation (SPM) is a nonlinear optical effect of light–matter interaction.An ultrashort pulse of light, when travelling in a medium, will induce a varying refractive index of the medium due to the optical Kerr effect. This variation in refractive index will produce a phase shift in the pulse, leading to a change of the pulse's frequency spectrum. Self-phase modulation is an important effect in optical systems that use short, intense pulses of light, such as lasers and optical fiber communications systems. Self-phase modulation has also been reported for nonlinear sound waves propagating in biological thin films, where the phase modulation results from varying elastic properties of the lipid films.
