A general design principle is presented for making finiteheight photonic crystal waveguides that support leakagefree guidance of light over large frequency intervals. The large bandwidth waveguides are designed by introducing line defects in photonic crystal slabs, where the material in the line defect has appropriate dispersion properties relative to the photonic crystal slab material surrounding the line defect. A threedimensional theoretical analysis is given for largebandwidth waveguide designs based on a siliconair photonic crystal slab suspended in air. In one example, the leakagefree singlemode guidance is found for a large frequency interval covering 60% of the photonic bandgap.
