    Abstract: Disclosed is an optical delay element that makes use of a line-defect waveguide of a photonic crystal, in which long optical delay time and small group speed dispersion are rendered compatible with each other and in which waveform distortion that might otherwise be produced in processing an ultra-high speed signal is eliminated. Two line-defect waveguides 5 and 11, having different pillar diameters and group velocity dispersions of opposite signs, are interconnected by a line-defect waveguide 8, the pillar diameters of which are gradually varied from one 5 of the line-defect waveguides to the other line-defect waveguide 11, such as to compensate for group speed dispersion as well as to maintain an optical delay effect.

    Abstract: A thermo-optic phase shifter includes a substrate having a cavity formed into an upper region of the substrate. The thermo-optic phase shifter includes an optical waveguide disposed above the substrate. The optical waveguide extends across and above the cavity. The thermo-optic phase shifter also includes a heater device disposed along a lateral side of the optical waveguide. The heater device extends across and above the cavity. The cavity is formed by an undercut etching process after the optical waveguide and the heater device is formed. The optical waveguide can be formed to include one or more segments that pass over the cavity. Also, a second heater device can be included such that the one or more segments of the optical waveguide that extend over the cavity are bracketed by heater devices. Thermal transmission structures can be included to enhance heat transfer between the heater device(s) and the optical waveguide.
