摘要： A dispersion compensator comprising a VIPA is configured so as to reflect light with each wavelength at an angle varying depending on wavelength when the light is reflected off a mirror. When being coupled at the end of an input fiber, the light with each wavelength is coupled at a specific angle. If the light is coupled with the fiber at a specific angle, coupling efficiency degrades. Therefore, in this case, coupling loss increases. Light having a wavelength with high transmittance in the VIPA is coupled with the fiber at a large angle, while light with a low transmittance is efficiently coupled with the fiber at a small angle or no angle. In this way, the round-top wavelength characteristic of the VIPA can be leveled.
摘要翻译：包括VIPA的色散补偿器被配置为当光从反射镜反射时以每个波长的光以与波长有关的角度变化。当在输入光纤的端部耦合时，每个波长的光以特定角度耦合。如果光以特定角度与光纤耦合，则耦合效率降低。因此，在这种情况下，耦合损耗增加。在VIPA中具有高透射率的光以大角度与光纤耦合，而具有低透射率的光以小角度或无角度与光纤有效耦合。以这种方式，VIPA的圆顶波长特性可以被平整。

摘要： Light input from a single-mode fiber is collected into linear light beams by a line focuser, and collected on a VIPA element. A light beam output from the VIPA element is made to pass through a space filter having a predetermined transmission loss characteristic, and focused on a mirror with a focusing lens. The light is reflected by the mirror, again passes through the space filter via the focusing lens, enters the VIPA element, and again enters the single-mode fiber via the line focuser. The insertion loss wavelength characteristic of the wavelength dispersion compensator using the VIPA element is optimized by being superimposed on the transmission loss characteristic of the space filter.

摘要： A VIPA plate having a configuration where a translucent reflection film and a total reflection film are respectively arranged on one side and the other side of a transparent parallel plate can be used as a wavelength dispersion compensator by using a special mirror and a lens. However, the transparency characteristic of the wavelength dispersion compensator using such a VIPA plate is a periodical characteristic which is asymmetric with a central wavelength in a wavelength regime. Accordingly, not parallel light but converged or diverged light having angular dispersion is input to an etalon plate, so that a filter whose transparency characteristic is an asymmetric periodical characteristic which is reverse to the VIPA plate is configured for the central wavelength in the wavelength regime. With this filter, the transparency characteristic of the wavelength dispersion compensator using the VIPA plate is optimized.

摘要： Rays of light having respective wavelengths angular-dispersed and output from a VIPA plate are collected by a lens, and diffracted by a grating pair which is an optical path shift generation unit and optical path shift amount variation unit, and have a shift in a path of rays having different wavelengths. When the rays are reflected by a dispersion leveling three-dimensional mirror and input into the VIPA plate again, they are received by portions having different dispersion compensation amount of the three-dimensional mirror, thereby realizing different amounts of wavelength dispersion for respective wavelengths, and independently adjusting an amount of wavelength dispersion of the entire wavelengths of the WDM rays and the wavelength dispersion slope.

摘要： In a method for producing a silicon single crystal by Czochralski method, the single crystal is grown with controlling a growth rate between a growth rate at a boundary where a defect region detected by Cu deposition remaining after disappearance of OSF ring disappears when gradually decreasing a growth rate of silicon single crystal during pulling and a growth rate at a boundary where a high oxygen precipitation Nv region having a density of BMDs of 1×107 numbers/cm3 or more and/or a wafer lifetime of 30 μsec or less after oxygen precipitation treatment disappears when gradually decreasing the growth rate further. Thereby, there is provided a silicon single crystal which does not belong to any of V region rich in vacancy, OSF region and I region rich in interstitial silicon, and has excellent electrical characteristics and gettering capability, so that yield of devices can be surely improved, and also an epitaxial wafer.
