In this paper, we propose a structure with cascaded two photonic crystal line-defect waveguides to reduce group velocity dispersion (GVD) of slow light. The width of the line-defect waveguides is tuned to obtain the two matched dispersion relations, where one of the dispersion relations has a maximum point with zero group velocity and large positive GVD; the other has a minimum point with zero group velocity and large negative GVD. The waveguides have ultra slow light with the group velocity 0.0012c. Finite-difference time-domain simulation demonstrates that the spreading of the slow light pulse in the first waveguide can be recovered by the dispersion compensation of the second waveguide with positive GVD.

Crescent scatterers possess the properties of anisotropy and multiple degrees of freedom. With plane-wave expansion method (PWE), the slow light effect with high ngand low dispersion can be achieved by optimizing the structure parameters of photonic crystal waveguide with line defect, such as changing the radius of two circles and center distance. Slow light with low dispersion can be obtained by these methods, which implies that choosing suitable scatterers and adjusting their parameters can efficiently achieve slow light with high ng and low dispersion.
