Nonlinearity Coefficients of Multimode Fibers

The dataset contains design parameters and nonlinear coefficients for sets of multimode optical fibers, from single-mode fibers to multimode fibers with thousands of modes, for the purpose of long-haul optical communications. The nonlinearity coefficients belong to two types of fibers analyzed in the related paper [Carniello24]: 1- the MMFs which have been considered to compute scaling laws and bounds on the nonlinear parameter γ κ; 2- a number of optimized and manufactured MMFs proposed in the literature.
For both groups, intermodal effective areas (among which the fundamental mode effective area), the Manakov nonlinear coefficient κ for the strong coupling regime (and the matrix of nonlinearity coefficients κ for the intra-modal group coupling regime for graded-index fibers), the nonlinearity coefficient γ κ (and the matrix of nonlinear coefficients γ κ for graded-index fibers) are provided. For the first group of fibers, core radius, refractive index difference, and numerical aperture are additionally given.
The analytically derived values of the nonlinear coefficient γ κ and the matrix of nonlinear coefficients γ κ for graded-index fibers are included.
A thorough description is given in the following paper: [Carniello24] Carniello P., Ferreira F. M., Hanik N., " Nonlinear Coupling Coefficients in Multimode Fibers for the Strong Coupling Regime Within Mode Groups and Across Mode Groups" , submitted to IEEE Journal on Selected Areas in Communications, 2024.
