Paper Abstract

Experimentally obtained spectral dependencies of an optical signal influenced by intermodal interference in a fiber under various conditions (for example, different lengths or different fibers) are presented. It is shown that the difference between the propagating constants of the first two modes can be obtained from the measured spectrum. The obtained results illustrate the usefulness of such investigation for determination of basic parameters of fibers, especially for investigating the homogeneity of a produced fiber.
