Abstract
Wide band and low dispersion slow light in optofluidic infiltrated photonic crystal waveguide has been theoretically demonstrated. By adjusting the refractive indices of infiltrated optofluidic in the nearest two rows of air holes beside the defect waveguide and tuning the radius of bulk holes, the group index and bandwidth can be enlarged effectively at the same time. Considering the restricted variation of group index ng within ±10%, the flat band slow light at any group index from 17.80 to 77.55 with large normalized delay bandwidth product staying in the range of 0.32 to 0.36 has been obtained. The most attractive is that there is a stable bulk hole r=0.328a as the refractive index of second row holes n2 changed for optimized slow light performances with large NDBP in large ng range.
