Hybrid dual-cladding photonic crystal fiber with high birefringence

Li Zhiquan; Li Sha; Hao Rui; Li Xiaoyun; Zheng Wenying

In this paper, a kind of hybrid cladding photonic crystal fiber was proposed. The model field distribution, birefringence, confinement loss and chromatic dispersion of fiber fundamental mode were simulated by multipole method. It was found that the newly designed fiber shows relatively higher birefringence and lower confinement loss. Then the birefringence and confinement loss of the hybrid cladding photonic crystal fiber were dominated by cladding air holes in the fiber. Simulation results show that the dispersion and dispersion slope are both negative over C band and L band. The birefringence is higher than 10-2, and the confinement loss is lower than 10-5 dB/m under the condition of =1.0 m,d1=d2=d3=0.8 m at the wavelength of 1.55 m.
