Graded index fiber
WebA step-index profile is approached in the limit of large α. A parabolic-index fiber corresponds to α = 2. It is easy to understand qualitatively why intermodal or multi path dispersion is reduced for graded-index fibers. As shown in the above picture, three different rays take three different paths. The path is longer for more oblique rays ... WebIn graded-index flbers the total internal re°ection is replaced by periodic refocusing (see also graded-index lens). A more accurate description of light propagation in flbers has …
