摘要： The present invention is a method for producing a single crystal of which a whole plane in a radial direction is a defect-free region with pulling the single crystal from a raw material melt in a chamber by Czochralski method, wherein a pulling condition is changed in a direction of the crystal growth axis during pulling the single crystal so that a margin of a pulling rate is always a predetermined value or more that the single crystal of which the whole plane in a radial direction is a defect-free region can be pulled. Thereby, there can be provided a method for producing a single crystal in which when a single crystal is produced by CZ method, the single crystal of which a whole plane in a radial direction is a defect-free region entirely in a direction of the crystal growth axis can be produced with stability.

摘要： A wavelength dispersion compensating apparatus of the invention comprises: a VIPA plate capable to output incident lights at different angles according to wavelengths; a variable dispersion diffraction grating which can angularly disperse the lights of respective wavelengths output from the VIPA plate, in a direction substantially perpendicular to a direction of angular dispersion in the VIPA plate and also capable to change an amount of the angular dispersion; a light return apparatus which condenses the output lights from the variable dispersion diffraction grating and reflects them by a mirror, to return them to the VIPA plate side; and a stage rotation mechanism which rotates a movable stage on which the lens and the mirror are mounted, according to a diffraction angle in the variable dispersion diffraction grating, so as to enable wavelength dispersion and wavelength dispersion slope to be given to a WDM light, to be changed independently. As a result, it becomes possible to compensate for, over a wide wavelength band, the wavelength dispersion and wavelength dispersion slope of the WDM light, which are propagated through an optical fiber to be accumulated.

摘要： An airgap type etalon has a higher degree of design freedom of a wavelength-temperature characteristic so that such a wavelength-temperature characteristic can be freely adjusted. The airgap type etalon includes a fixing block having one flat surface, and a transparent parallel flat plate having parallel flat surfaces formed with an antireflection coating and a reflection augmenting coating thereon, respectively. The flat surface at the antireflection coating side is joined to the flat surface of the fixing block. A parallel flat spacer has a thickness greater than that of the transparent parallel flat plate and an expansion coefficient different from that of the transparent parallel flat plate. One of the flat surfaces of the parallel flat spacer is joined to the flat surface of the fixing block. A transparent flat plate has opposite flat surfaces formed with an antireflection coating and a reflection augmenting coating thereon, respectively. The flat surface at the reflection augmenting coating side is joined to the other of the flat surfaces of the parallel flat spacer, wherein a Fabry-Perot interferometer is formed based on an airgap positioned between the flat surface of the transparent parallel flat plate and the flat surface of the transparent flat plate, which flat surfaces face each other.
