Abstract

A transformation operator is constructed for the calculation of the modal power distribution changes caused by abrupt inhomogeneity in multimode fibers. Simplification and practical applicability of the analysis are achieved by using the mode-continuum approximation. Thus, the model enables taking into account the fiber inhomogeneities of the following types: fiber lateral offset, core diameter mismatch, numerical aperture difference, and joints of fibers with different index profiles. The admission of an arbitrary refractive index profile, input modal power distribution, and parameters of fiber mismatch is an advantageous feature of the model. The operator is applied to calculations of power loss at joints between different multimode fibers, and the results of the calculations are shown to be in a good agreement with experimental data.
