Graded-index fiber - Wikipedia

WebThe index profile of a core of multimode graded index fiber is given by? N (r) = n1 [1 – 2Δ(r²/a)²]½; r a N (r) = n1 [1 – 2Δ(r²/a)²]½; r 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 optical axis of the fiber. Because parts of the core closer to the fiber axis have a higher refractive index than the parts near the cladding, light rays follow sinusoidal paths down the fiber. The most common refractive index profile for a graded-index fiber is very nearly parabolic. The parabolic profile results in conti… canned abalone at costco
