摘要： This invention relates to a sintering furnace for the production of a quartz preform which can be used for carrying out dehydration, fluorine-addition and/or sintering of a porous quartz soot preform prepared by a flame hydrolysis method such as a VAD method or a OVD method, and in particular, to such a furnace in which joints in a long furnace muffle so long that fabricating it as open body is impossible can be maintained fully gas-tight, so that it is possible to prevent H.sub.2 O, O.sub.2 and other impurities in the air from entering the muffle from outside, and corrosive and poisonous gases in the muffle are prevented from leakage to outside the muffle. This sintering furnace has a muffle of high purity carbon, the inner wall and/or outer wall of which is coated with a gas-impermeable film, which muffle is a cylinder with an axis in the longitudinal direction and divided into a plurality of parts in the longitudinal direction, the parts each having the upper and lower ends finished so as to be flat and abutting adjacent parts sealed by a carbon gasket between them, and further has an air cylinder for pressing the parts together in the axial direction with a uniform force around the circumference of the muffle.

摘要： Based on an intermediate 20A in which a cladding portion 22 is formed on the outer periphery of a core portion 21, a pair of holes 23 and 24 are provided parallel to the z axis on both sides of the core portion 21 within the cladding portion 22, and an intermediate 20 is thereby fabricated. In this intermediate 20, a width Ry in the y-axis direction is made smaller than a width Rx in the x-axis direction. Moreover, a cylindrical stress applying part 33 is inserted into a hole 23 of the intermediate 20, and a cylindrical stress applying part 34 is inserted into a hole 24 thereof. Thus, a preform 40 is formed. These materials are drawn and integrated together, and a polarization maintaining optical fiber is thereby manufactured.

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.
