摘要

This paper describes ultra-flattened chromatic dispersion and low confinement loss that can be achieved from a two defected rings square photonic crystal fiber (SPCF). An efficient full vector modal solver based on the finite difference method with anisotropic perfectly matched layers absorbing boundary condition is used for numerical analysis. The designed two defected rings index-guiding SPCF has a ultra-flattened dispersion of 0 ± 0.5 ps/(nm.km) in a wavelength range of 1.42 to 1.66 μm (240 nm band) which covers S+C+L telecommunication bands and extremely low confinement loss of less than 10~(-13) dB/m in a wavelength range of 1.3 to 1.7 μm. The proposed two defected rings index-guiding SPCF also shows promising dispersion tolerance and extremely low bending loss.
