摘要： The present invention relates to an optical fiber having a structure which allows further improvements to be made both in terms of lower reflectance and narrower bandwidth, and to a fiber grating type filter including the optical fiber. The optical fiber applied to the fiber grating type filter comprises a core region extending along a predetermined axis, and a cladding region provided on an outer periphery of the core region. The core region does not contain any photosensitive dopant which contributes to predetermined wavelength light photosensitivity as a glass property, but a part of the cladding region contain such a photosensitive dopant. By means of this composition, it is possible to form a grating, which has a grating plane slanted by a predetermined angle with respect to the optical axis, in a part of the cladding region surrounding the core region.

摘要： An optical fiber comprises a core region, an inner cladding region, and an outer cladding region. Each of the core region and inner cladding region is doped with GeO2, whereas the inner cladding region is also doped with F element. The core region has a refractive index higher than each of the refractive index of the inner cladding region and the refractive index of the outer cladding region. Each of the core region and inner cladding region doped with GeO2 has a UV photosensitivity. The deviation in concentration distribution of GeO2 added to the inner cladding region is so small that the deviation in UV photosensitivity in the inner cladding region is ±10% or less.

摘要： A force-feedback multidirectional input device includes a slider slidably supported by a support base and an operation knob joined to the slider. In a sliding operation, the slider operates in conjunction with actuating members included in a force-feedback unit. Therefore, a sense of force based on the sliding is fed back to the operation knob. Furthermore, the slider is elastically urged by coil springs toward an inner bottom surface of a housing space defined in the support base. In a depressing operation, the operation knob presses the support base downward against the urging force of coil springs. Therefore, a vertically movable member joined to the support base is moved downward along guide portions (convex rails and concave grooves). Thus, a push switch provided on a pedestal (circuit board) is pressed and activated by the vertically movable member.
