Polarization-mode properties of elliptical-core fibers and stress-induced birefringent fibers

Abstract

Polarization-mode properties of elliptical-core fibers and stress-applied single polarization fibers are clarified theoretically and experimentally. Normalized frequency dependence of modal birefringence and polarization-mode dispersion is measured, and the results are found to be in good agreement with the calculated results. It is revealed that the stress distribution over core and cladding has a strong influence on the polarization properties for the single-mode fibers examined here.
