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.

摘要： A print data conversion area can be created to reflect that all printed slips are not the same size. A printer includes a conveyance unit that conveys checks with one edge following a guide extending in the conveyance direction, a length detection unit that detects the length of the conveyed check in the conveyance direction, and a conversion area formation unit that creates a print data conversion area to which print data for the entire image to be recorded on the check is written. The conversion area formation unit determines the range of the conversion area with reference to a position corresponding to a particular position on the check using the detected length of the check in the conveyance direction.
