%X The bright soliton pulse propagation and the slow light delay time properties of 2D cubic and triangular lattice photonic crystal line defect waveguide (PCW) with circular Si-rods near the left edge of the guidedmode are investigated. By using the plane-wave expansion (PWE) method, the ralues of soliton required peak power P0 and delay time TS of the waveguided with different radii of the first two rows of Si-rods adjacent to the waveguide, r1 and r2, and waveguide width D are numerically investigated. Adjusting the waveguide structure can bring in optimized cubic and triangular lattice waveguide, of which P0 is reduced by 81.17% and TS is increased by 66.32% for cubic lattice waveguide; P0 is reduced by 73.7% and TS is increased by 67.63% for triangular lattice waveguide. These results show that the soliton transmission performance in the photonic crystal line defect waveguide can be effectivly optimized.
