Theoretical Analysis of Multimode Fiber Structures

摘要

This study examined propagation characteristics of a light beam in multimode fiber structures. Realistic fiber structures made with commercially available fibers such as those provided by Corning or ITT were studied. The resultant computer programs may be used readily to generate design data for structures made with realistic fibers with step or parabolic index profiles. It is believed that our unique approach based on the scalar-wave FFT method may be extended to treat problems dealing with nonlinear fibers or fibers with frozen-in statistically varying index profiles.
