Design optimization of a pure silica dual-core photonic crystal fiber for broadband dispersion compensation is proposed to match the relative dispersion slope of the standard single-mode fiber. The influence of the three diameters of the air-holes in the outer cladding upon the dispersive and slope-matched property is investigated and a dispersion value of −3179.9 ps·nm−1·km−1 at 1550 nm has been predicted. The dispersion of the standard single-mode fiber, which is 187 times the length of the dual-core photonic crystal fiber, can be compensated (to within 0.12%) over the entire C band / (to within 0.56%) over the 100-nm broadband centered at 1550nm.
