Polarization mode properties of a polarization-preserving fiber having elliptical stress-cladding with barrier layer around the core are clarified theoretically and experimentally. Normalized frequency dependence of modal birefringence and polarization mode dispersion were measured. It is found from theoretical and experimental results that the elliptical stress-cladding fiber has polarization-mode properties similar to those of the polarization-preserving fiber having isolated stress-producing lobes. Stress profiles of the elliptical stress-cladding fiber confirmed the polarization-mode properties of the fiber. The similarities of polarization-mode properties between the elliptical stress-cladding fiber and the fiber with stress-producing lobes are caused by similarities of differential stress profiles around the core regions between them.
