dc.description.abstract The birefringence of an optical fiber resulting from an asymmetry of the index profile is numerically evaluated using a finite-element method with a full-vectorial formulation. Such asymmetric index profiles, assumed to vary exponentially across the fiber core, could be induced during the writing of fiber Bragg gratings with UV side-exposure techniques. The results reveal that the birefringence is a quadratic function of the effective index change. An asymmetry coefficient near 0.4 /spl mu/m/sup -1/ maximizes the birefringence. The calculated photo-induced birefringence is negligible if the index change is lower than 5/spl times/10/sup -4/. However, the birefringence can reach 5/spl times/10/sup -6/ for large values of index change. The numerical method presented could be applied to the modeling of other asymmetric index profiles.
