Paper Abstract

As a rule, the low-mode optical fiber is excited by a linear polarized Gaussian beam. In this case a fundamental HE11 mode and LP11 field combination are propagated through the fiber. The complete field of free space is usually characterized by phase singularities. But in an optical fiber, the fields have complete polarizing structure. In this paper, vector singularities -- dislocations and disinclinations are studied. It is shown that a row edge dislocation of the LP11 mode is splitted into two circular polarized C+ and C- disclinations twisting in the opposite direction and two fixed linear polarizing disclination. The very birth and death events of these dislocations and disclinations determine the light propagation processes along the linearly polarized exciting low-mode fibers.
