• hollow-core photonic band-gap fiber (HC-PBF)
• finite element method (FEM)
• single polarization
• confinement loss

To improve the propagation quality in photonic crystal fibers, a novel dual elliptical assistant holes hollow fiber is proposed. Numerical model of confinement loss has been modeled by vector finite element method, then the core loss characteristics and the power ratio of the hollow fiber has been simulated and analyzed. The results show that the x-polarization confinement loss and the core power ratio are 0.06dB/m and 98.2% at 1550nm, respectively. By contrast, the y-polarization confinement loss is up to 243.34dB/m while the core power ratio is 47.86%. The novel optical fiber exhibits good single polarization characteristics and transmission characteristics, and the bandwidth range of single mode single polarization is 55nm. The novel optical fiber is very good to satisfy the requirement of single mode single polarization at the 1550nm.
