| Term (EN) | refractive index contrast (symb.: ∆) |
|---|
| Definition (EN) | A measure of the relative difference in refractive index of the core and the cladding of an optical fibre, given by :
"Δ"=(n_1^2-n_2^2)/(2n_1^2 )
where n1 and n2 are, respectively, the maximum in the core and the refractive index of the innermost homogeneous cladding. |
