| Term (EN) | power-law index profile, alpha profile (deprecated) |
|---|
| Definition (EN) | 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) = n_1^2 [1 — 2 ∆ (r/а)g]
r ≤ a 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 ∆ is a parameter which is the same as the refractive index contrast when the refractive index of the cladding is constant. |

| Term (SR) | indeks profil sa stepenovanom udaljenosti, alfa profil (zastarjelo) |
|---|
| Definition (SR) | Stepenovani indeks profil sa kvadratom indeksa prelamanja u jezgru koji se smanjuje u skladu sa zakonom koji uključuje stepenovanu udaljenost od ose.
n2 (r) = n_1^2 [1 — 2 ∆ (r/а)g]
r ≤ a gdje su:
n(r) je indeks prelamanja u funkciji radijusa,
n1 indeks prelamanja na osi,
a je radijus jezgra
g je parametar koji definiše oblik profila,
∆ je parametar koji je isti kao i kontrast indeksa prelamanja, kada je indeks prelamanja omotača konstantan. |
