Finite Element Analysis of Propagation Characteristics for An Octagonal Photonic Crystal Fiber (O-PCF)
An octagonal photonic crystal fiber (O-PCF) structure with eight air-holes on the first ring is proposed based on a unit isosceles triangle. The mode effective index and chromatic dispersion of the O-PCF are numerically investigated by employing the finite element method. It is found that under the same value of air filling fraction (AFF), the octagonal photonic crystal fiber has smaller mode effective index and higher amplitude of dispersion. On the other hand, the dispersion of O-PCF can be easily controlled through adjusting appropriately the air-hole pitches and air-hole diameters.
