Definition: | the quantity which characterizes that part of profile dispersion due to a variation of refractive index contrast with wavelength given by: $P\left(\lambda \right)=\frac{{n}_{1\text{\hspace{0.17em}}}\lambda \text{\hspace{0.17em}}\text{d}\text{\Delta}}{{N}_{1}\text{\hspace{0.17em}}\text{\Delta}\text{\hspace{0.17em}}\text{d}\lambda}$ where
Δ is the refractive index contrast, | ||

$P\left(\lambda \right)=\frac{{n}_{1\text{\hspace{0.17em}}}\lambda \text{\hspace{0.17em}}\text{d}\text{\Delta}}{{N}_{1}\text{\hspace{0.17em}}\text{\Delta}\text{\hspace{0.17em}}\text{d}\lambda}$

where

*n*_{1} is the maximum refractive index of the core,

*N*_{1} is the group index corresponding to *n*_{1} calculated from the formula:

*N*_{1} = *n*_{1} = *λ* (d*n*_{1} / d*λ*)

Δ is the refractive index contrast,

*λ* is the wavelength in vacuum
