Polarization Properties of Polymer Photonic Crystal Fiber with Square-Lattice Elliptical Air-Hole

Abstract:

A novel type of photonic crystal fiber for high birefringence and zero-walkoff is proposed based on polymer, the fiber is composed of a solid polymer core and a cladding with square lattice elliptical air-holes along the fiber length. The optical birefringence and polarization-dependent leakage loss are studied numerically based on the full-vector finite element method(FEM). Numerical results show that the proposed fiber has heightened modal birefringence of the order of 10^-2; and the leakage loss is reduced to 0.08dB/m at wavelength of 0.65μm when it has 10 rings of elliptical air-holes. So the proposed PCFs may be useful in the field of high birefringence polarization-maintaining optical communication.
