Abstract
A fiber cross-section altering induces eigen mode structure deformation. In turn, this field structure deformation may results changing of eigen guided vortex features or their completely decay of the vortices structure. In the given paper, there introduces the topological deformation coefficient Q for a vortex behavior description into perturbed low-mode fibers. It is found out, that even small fiber cross-section deformations can course a large vortex field structural changing. If this deformations are uniformly distributed over a fiber, Q value is periodically altered along the waveguide. Similar vortex structure deformation appears in coupled fibers where the fibers are nearly placed each other.
