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