profile dispersion parameter
the quantity which characterizes that part of profile dispersion due to a variation of refractive index contrast with wavelength given by:

P( λ )= n 1 λdΔ N 1 Δdλ MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLnhiov2DGi1BTfMBaeXatLxBI9gBaerbbjxAHXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeqabiGaciGacaqadmaadaqaaqaaaOqaaiaadcfadaqadaqaaiabeU7aSbGaayjkaiaawMcaaiabg2da9maalaaabaGaamOBamaaBaaaleaacaaIXaGaaGPaVdqabaGccqaH7oaBcaaMc8ocbaGaa8hzaGGaaiab+r5aebqaaiaad6eadaWgaaWcbaGaaGymaaqabaGccaaMc8UaaeiLdiaaykW7caqGKbGaeq4UdWgaaaaa@4C09@

where

n1 is the maximum refractive index of the core,
N1 is the group index corresponding to n1 calculated from the formula:

N1 = n1 = λ (dn1 / dλ)

Δ is the refractive index contrast,
λ is the wavelength in vacuum

facteur de dispersion de profil, m
grandeur qui caractérise la dispersion de profil due à la variation du contraste d'indice en fonction de la longueur d'onde par l'expression:

P( λ )= n 1 λdΔ N 1 Δdλ MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLnhiov2DGi1BTfMBaeXatLxBI9gBaerbbjxAHXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeqabiGaciGacaqadmaadaqaaqaaaOqaaiaadcfadaqadaqaaiabeU7aSbGaayjkaiaawMcaaiabg2da9maalaaabaGaamOBamaaBaaaleaacaaIXaGaaGPaVdqabaGccqaH7oaBcaaMc8ocbaGaa8hzaGGaaiab+r5aebqaaiaad6eadaWgaaWcbaGaaGymaaqabaGccaaMc8UaaeiLdiaaykW7caqGKbGaeq4UdWgaaaaa@4C09@

n1 est l'indice de réfraction maximal dans le coeur,
N1 est l'indice de groupe du coeur, calculé par la formule:

N1 = n1 = λ (dn1 / dλ)

Δ est le contraste d'indice,
λ est la longueur d'onde dans le vide
