Stress-induced birefringence and modal birefringence of single-mode specialty optical fibers with three stress regions are numerically analyzed by the vector finite element method.Stress distribution and stress-induced birefringence distribution of three kinds of optical fibers with different cross structures are presented and compared, and the influence on the stressinduced birefringence by temperature change are analyzed as well.The results show that the fibers with three-stress regions have a lower linear birefringence, which is very important for the fabrication of the circular polarization-maintaining fiber with high performance drawn from the same fiber preform by using the spinning method.
