A novel kind of scattererscylinder segments has been designed. Based on this design, a series of photonic crystal waveguides, including structures of dielectric pillars in air and structures of air holes in dielectric, are fabricated on silicon wafer. The measurement results demonstrate that the structures of dielectric pillars in air can form band gaps more easily than the structures of air holes in dielectric, and the former can also tune the widths and positions of the band gaps by changing the parameter e. For the same structure of dielectric pillars in air, the band gap position in the optical transmission spectra moves toward the shorter-wavelength edge when the angle of incidence along the long axis becomes larger, indicating that the structure has the property of anisotropy.
