• Cladding (metalworking) — Cladding is the bonding together of dissimilar metals. It is distinct from welding or gluing as a method to fasten the metals together. Cladding is often achieved by extruding two metals through a die as well as pressing or rolling sheets… …   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

• 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

• 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

• 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

• 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

• Gradienten-Index-Linse — Eine Gradientenlinse mit parabolischer Änderung der Brechzahl (n) entlang des radialen Abstandes (x). Die Linse bündelt Licht in gleicher Weise wie eine konventionelle Linse. Die Gradientenoptik ist ein Teilbereich der Optik und befasst sich mit… …   Deutsch Wikipedia
