For the group indices, the dependence on the mode index is different: here, we often get higher values for higher-order modes, indicating that the light pulses in those modes propagate with lower velocity.
Guide Higher-Order Modal Dispersion in Graded-Index Multimode Fiber
Previously, we proposed a field-coupling model for propagation in graded-index multimode fiber (MMF), analogous to the principal states model for polarization-mode dispersion (PMD) in single-mode fiber.
