In this paper, a photonic crystal slab waveguide with wideband slow light, large group index (ng), and very low group velocity dispersion (GVD) has been presented. The structure is designed by shifting the first row of the air holes adjacent to the waveguide center in the longitudinal direction, and optofluidic infiltration in the second row. By applying optimized parameters for the two rows, a flexible control of ng(17.5<ng<133) with large bandwidth (2nm<Δλ<23nm) is obtained. The GVD decreased at the range of 1022s2/m. Numerical simulations are performed by the three-dimensional plane-wave expansion method.
