Refractive index contrast — Refractive index contrast, in an optical fiber, is a measure of the relative difference in refractive index of the core and cladding. Refractive index contrast, Delta;, is given by Delta; = ( n 12 n 22)/(2 n 12), where n 1 is the maximum… … Wikipedia
Refractive index profile — A refractive index profile is the distribution of refractive indices of materials within an optical fiber. Some optical fiber has a step index profile, in which the core has one uniformly distributed index and the cladding has a lower uniformly… … Wikipedia
