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
Cladding (fiber optics) — Cladding is one or more layers of material of lower refractive index, in intimate contact with a core material of higher refractive index. The cladding causes light to be confined to the core of the fiber by total internal reflection at the… … Wikipedia
Cladding mode — In fiber optics, a cladding mode is a mode that is confined to the cladding of an optical fiber by virtue of the fact that the cladding has a higher refractive index than the surrounding medium, which is either air or the primary polymer overcoat … Wikipedia
cladding — The transparent material, usually glass, that surrounds the core of an optical fiber. Cladding has a lower refractive index than the core and so prevents the light signal from spreading out due to modal dispersion, by reflecting the signal… … Dictionary of networking
Step-index profile — For an optical fiber, a step index profile is a refractive index profile characterized by a uniform refractive index within the core and a sharp decrease in refractive index at the core cladding so that the cladding is of a lower refractive index … Wikipedia
Graded-index fiber — In fiber optics, a graded index or gradient index fiber is an optical fiber whose core has a refractive index that decreases with increasing radial distance from the fiber axis (the imaginary central axis running down the length of the… … Wikipedia
Power-law index profile — For optical fibers, a power law index profile is an index of refraction profile characterized by : n(r) = egin{cases} n 1 sqrt{1 2Deltaleft({r over alpha} ight)^g} r le alpha n 1 sqrt{1 2Delta} r ge alpha end{cases}whereDelta = {n 1^2 n 2^2 over … Wikipedia
stepped-index fibre — noun (telecommunications) An optical fibre in which there is an abrupt transition from the higher refractive index of the information bearing core to the lower refractive index of the cladding (cf ↑graded index fibre) • • • Main Entry: ↑step … Useful english dictionary
