Abstract

We investigate the mode structure of a weakly guiding anisotropic optical fiber, in which the anisotropy axis rotates in a transverse plane with z increasing. It is demonstrated that at certain values of the anisotropy pitch the spin-orbit coupling is in effect damped and 1=1 modes of the fibers are almost pure linear optical vortices. Polarization corrections to the propagation constant are found. It is demonstrated that in some limiting cases the rise of such corrections can be explained as a manifestation of topological Pancharatnam-Berry’s phase.
