摘要： There is provided a slant short-period grating which is obtainable by irradiating light onto an optical fiber whose core is formed from quartz glass to which has been doped a photosensitive dopant that changes a refractive index of the quartz glass by light irradiation, and whose clad has one or two or more layers with at least the layer that is adjacent to the core being a photosensitive layer formed from quartz glass to which has been doped a photosensitive dopant that changes a refractive index of the quartz glass by light irradiation. In this slant short-period grating a grating portion is formed by changing the refractive index of the photosensitive layer of the clad and the core at a predetermined grating period along a longitudinal direction of the optical fiber by a predetermined slant angle. The diameter of the core is set to 5 &mgr;m or more, and the relative photosensitivity ratio of the core relative to the photosensitive layer of the clad that is adjacent to the core is designed so as to satisfy a predetermined formula. As a result, in the wavelength spectrum of transmitted light, loss peaks are obtained in a narrow frequency band.

摘要： A variable optical fiber grating is provided which is compact, and in which an amount of chromatic dispersion can be effectively varied without changing an operating center wavelength. Also provided is a dispersion compensator, which uses this variable optical fiber grating. The fixing member is formed by providing an outer cylinder 2 comprising a material with a lower coefficient of linear expansion around an inner cylinder 1 comprising a material with a higher coefficient of linear expansion, and an optical fiber grating is fixed in a groove 3 formed on the inner cylinder 1. By adjusting the fixing position of the optical fiber grating, an expansion coefficient and contraction coefficient of the optical fiber grating which follows the expansion and contraction of the material with the higher coefficient of linear expansion, differ along the longitudinal direction of the optical fiber grating, so that an amount of chromatic dispersion is controlled.

摘要： Prepared is an n− type semiconductor substrate 1 having a first principal surface 1a and a second principal surface 1b opposed to each other, and having a p+ type semiconductor region 3 formed on the first principal surface 1a side. At least a region opposed to the p+ type semiconductor region 3 in the second principal surface 1b of the n− type semiconductor substrate 1 is irradiated with a pulsed laser beam to form an irregular asperity 10. After formation of the irregular asperity 10, an accumulation layer 11 with an impurity concentration higher than that of the n− type semiconductor substrate 1 is formed on the second principal surface 1b side of the n type semiconductor substrate 1. After formation of the accumulation layer 11, the n− type semiconductor substrate 1 is subjected to a thermal treatment.
