Paper Abstract

It is studied structurally stable nonparaxial vector singular beams -- generic beams -- near an optical fiber input as solutions of Maxwell's equations. The beam behavior in a free space or a homogeneous isotropic medium is considered. Any variation of a beam Raylein length is turn out to change no number and form of phase and polarization singularities but to displace their coordinates. It is found that a field structure both of eigen modes in a free space and an optical fiber is much about the same. Nevertheless there exist an essential distinguished feature of generic fiber modes -- a spin-orbit interaction in a vortex field, that defines a polarization correction to a scalar propagation constant. It is the fact that enable us to divide fiber vortex sensors into two big groups: thermodynamics value devices and inertial navigation sensors.
