摘要： An optical delay element including a photonic crystal line defect optical waveguide is disclosed that has a large group refractive index and has small or nearly constant wavelength dispersion of the group refractive index in a wide wavelength region for practical use. The optical delay element includes a line defect optical waveguide formed in a photonic crystal structure, and the volume of the line defect optical waveguide is less than the volume of a single line defect optical waveguide. Thereby, the waveguide band of the line defect optical waveguide has two zero points in the third order dispersion curve of the line defect optical waveguide, and the sign of the third order dispersion curve is inverted near the zero points. Therefore, the waveguide band of the line defect optical waveguide is modified, and this enables expansion of the wavelength region having a large group refractive index, small wavelength dispersion of the group refractive index, and small wavelength dispersion of the speed of optical pulses.

First and second hollow layers are formed at first and second surfaces of a piezoelectric substrate to form first and second cavities around first and second electrodes respectively. The first and second cavities each have a uniform width and extend between a first surface and an opposing second surface of the first and second hollow layers respectively, around vibration portions of the piezoelectric element. First and second sealing layers are each formed on the second surface of the first and second hollow layers to seal the first and second cavities.
