| Abstract: | In order to obtain a new flat dispersion photonic crystal fiber with low confinement loss, six octagonal rings of air holes in different diameters of d1, d2 and d3 were designed in the cladding of the fiber. Effect of the structure parameters on the dispersion and confinement loss was simulated by means of multi-pole method. The results show that the dispersion is among -0.1ps/(kmnm)~ 0.58 ps/(kmnm) in the wavelength range of 1.3m to 1.72m.The confinement loss is 0.16dB/km at 1.55m. So the special octagonal structure is more suitable for photonic crystal fibers with flat dispersion and low confinement loss. The results are useful for application of photonic crystal fibers in the optical communication. |
