We present a novel and robust design for a photonic crystal fiber with flattened dispersion, a highly nonlinear coefficient, and low confinement loss for its dual concentric core structure. The proposed fiber has a modest number of design parameters. Analysis results show that the proposed eight-ring photonic crystal fiber is obtained with a nonlinear coefficient greater than 33 W 1 km 1 and a near-zero dispersion slope of 7.828 × 10 4 ps / nm 2 / km at 1550 nm . Ultraflat dispersion with a value between 1.380 and + 0.9860 ps / nm / km and a superlow-order confinement loss of 10 4 dB / km are simultaneously obtained ranging from 1400 to 1625 nm . For practical fabrication, the influence of random imperfections of airhole diameters on dispersion and nonlinearity is discussed to verify the robustness of our design.
