Abstract
We propose a novel embedded-core hollow optical fiber composed of a central circular air hole and a semi-elliptical core embedded in an annular cladding. Both the phase birefringence and group birefringence are investigated based on the finite element method (FEM). The embedded-core hollow optical fiber has polarization-preserving properties. The birefringence magnitude of the proposed fibers is the same order as that of the side-hole optical fiber. The theoretical results reveal that the birefringence of embedded-core hollow optical fibers can reach the order of 10-4. The group birefringence of the fiber is obtained by using the wavelength scanning technique and can reach 4.7×10-5. The measurement results are basically consistent with the theoretical simulations.
