Paper Abstract

High birefringence optical fibers such as elliptical core fibers and many highly birefringent photonic crystal fibers usually broke the symmetry of circle by introduced C symmetry. In this paper, a novel microstructured high birefringence optical fiber with C symmetry is proposed. Four air holes were introduced into the core of a circular optical fiber, circular symmetry was broken, and the core of this kind of optical fibers only maintained C symmetry. The degeneracy fundamental mode LP01 was split into two modes LPx01, LPy01 because the symmetry of C1v is lower than that of C , the difference between the patterns of the two modes field was larger. Using multipole method, we calculated the propagation constants of modes LPx01 and LPy01, the modal birefringence B is to the magnitude of 10-2 which is almost tenfold greater than that of many highly birefringence photonic crystal fibers. The other advantage of this kind of optical fibers is that the fabrication of fibers with a few air holes is easier than that of photonic crystal fibers with many air holes.
