Graded index optical fibres
WebIn multimode operation of an optical fiber having a power-law refractive index profile, the approximate number of bound modes (the mode volume), ... For a step-index fiber, the mode volume is given by V 2 /2. For single-mode operation, it is required that V < 2.4048, the first root of the Bessel function J 0. See also. WebDec 22, 2024 · However, things are different if one uses a graded-index multimode fiber. Although the light rays travel in different modes as well, the modal dispersion will be greatly decreased because of the various light propagation speeds.
