A novel design of high birefringent photonic crystal fiber based on schott glass with elliptical air holes in the core and cladding is proposed,and two circular air holes are introduced in the innermost layer of the cladding.Using the finite element method，its birefringence,confinement loss and dispersion characteristics are investigated simultaneously by changing the pitch of air holes and ellipticity of elliptic air holes .Numerical results show that the value of birefringence can be improved by introducing a small elliptical air hole in the core,the birefringence and confinement loss are respectively about 5.22×10-2 and 8.82×10-10 dB/m at 1.55 μm with the cladding air holes pitch size of 1.6 μm and the ellipticity ratio of 0.5.In addition,the fiber keeps normal dispersion in a wavelength range from 1.0 μm to 2.2 μm.In conclusion,this proposed photonic crystal fiber are significant for the further research on the new background material photonic crystal fiber.
