Abstract
The existence of eigen polarization modes in a twisted single-mode fiber with an elliptical core is verified theoretically and experimentally. The eigen polarization modes are transmitted without degradation in the degree of polarization. Ellipticity and the principal axis orientation of the eigen polarizations are determined by fiber-core ellipticity and fiber twist. The ellipticity of the eigen polarization modes remains unchanged for a fixed core ellipticity and twist effect, even after long-distance transmission, whereas the orientation of the principal axis varies according to the fiber twist angle. For a sufficiently large twist rate, all the incident polarizations maintain their ellipticity of polarization.
