Graded index fiber
WebTypical core diameters of graded-index fibers are 50, 62.5, and 100 µm. The main application for graded-index fibers is in medium-range communications, such as local area networks. Multimode step index … WebThe step-index fiber was created using two overlapping circle structures of silica (n=1.4) and a dielectric defined with index n=1.44. The graded-index fiber was created using a circle structure with index given by the equation sqrt (4* (1- (x^2+y^2)/40^2)). Results Analytical Solutions
