Paper Abstract

In the article we present a computer simulation and experimental data of excitation coefficients of fiber eigen modes. As experimental samples we chose two types of weakly guiding fibers: isotropic and highly birefringent ones with a round cross-section. Calculation of the mode weights is accomplished by means of a geometrical analysis of a beam image structure behind the fiber. In particular, we employed geometrical properties of intensity-level-lines near a fiber core. Such approach enabled us to estimate mode weights as well different mode groups as separate modes inside the group.
