RESUMO
In this paper a highly polarization maintaining birefringent photonic crystal fiber at telecommunication window is reported via Full-Vectorial Finite Element Method (FV-FEM). By taking triangular lattice of three ring hexagonal structure PCF with suitable designing parameters such as symmetrical elliptical hole along radial axis of ellipticity a/b=5µm, air hole diameter d=1µm and pitch Λ=2.3µm, high birefringence (2.437×10-3) with small effective mode area(9.47µm²) and beat length (0.64cm) are found at wavelength 1.55µm.
