Title (EN) OPTICAL FIBRE OPTIMIZED FOR THE REDUCTION OF NONLINEAR EFFECTS
(FR) FIBRE OPTIQUE OPTIMISÉE POUR LA DIMINUTION DES EFFETS NON LINÉAIRES
Abstract:
(EN) An optical fibre designed to simultaneously attenuate the effect of modulation instability and stimulated Raman scattering. A first solution proposes to use non-zero dispersion shifted fibres in the normal dispersion regime to reduce both influences at the same time. A further solution proposes to implement corresponding filter elements in the signal line. A still further solution proposes to additionally provide absorber elements for the Raman wavelengths or to design the core as a leaky one for these wavelengths.
(FR) La présente invention se rapporte à une fibre optique conçue pour atténuer simultanément l'effet de l'instabilité de modulation et de la diffusion Raman stimulée.
