Definition: a graded index profile with the square of refractive index in the core decreasing according to a law involving a power of the distance from the axis.

n2 (r) = n21 [1 – 2 Δ (r / а)g]

ra where :
n(r) is the refractive index as a function of radius,
n1 is the refractive index on axis,
a is the core radius,
g is a parameter that defines the shape of the profile
and Δ is a parameter which is the same as the refractive index contrast when the refractive index of the cladding is constant
