It is shown experimentally and theoretically that the interconversion dynamics of the field of the LP11 mode combination of a few-mode optical fiber is determined by the interaction of circularly polarized pure edge C + and C disclinations. The C + and C disclinations correspond to characteristics of the field for which the right-or left-circularly polarized electric field goes to zero. During propagation the uniformly linear-polarized dislocations D y break down into four C + disclinations travelling in opposite senses. When each pair of C and C + disclinations meet they annihilate each other and form linear polarization. The field of the linearly polarized disclinations thus created sums up out of phase into the original field and forms a uniformly linearly polarized field with D x dislocations.
