Abstract. We numerically demonstrate a high-nonlinearity single-mode holey fiber with flattened dispersion around the Ti-Za laser band at 800 nm. The dispersion profile of the fiber has the shape of a quadratic curve, which reaches its maximum 5.96 ps.km⁻¹ .nm⁻¹ at 800 nm and its minimum –0.897 ps.km⁻¹ .nm⁻¹ at both 750 and 850 nm. The nonlinear coefficient is 170 W⁻¹ km⁻¹ at 800 nm and no higher order modes exit. A six-layer air-hole cladding ensures a loss less than 0.067 db/m in the 750 to 850 nm range. Two more air-hole rings will reduce the loss to below 0.1 db/km.
