Abstract: PROBLEM TO BE SOLVED: To make doped or undoped pure silica glass material. SOLUTION: (I) At least one stream of glass soot particles comprising silica is provided by a burner 315. (II) At least one stream of the glass soot particles is directed to an essentially planar deposition supporting surface of a deposition substrate 301 rotating about a rotation axis, such that at least one layer of glass soot is deposited on the deposition supporting surface to form a soot preform 303. In the step (II), the burner 315 is allowed to move relative to the deposition supporting surface, and the velocity of the burner 315 relative to the deposition supporting surface is modulated such that in at least half of the area of the layer of glass soot deposited, local soot density variation through at least the center half thickness is low.

Abstract: PROBLEM TO BE SOLVED: To reduce attenuation of a glass optical fiber due to heat aging and Rayleigh scattering in a heat treatment of the fiber. SOLUTION: In the method for forming an optical fiber, the optical fiber is formed by drawing at ≥10 m/sec draw rate from a heated glass source (block 10) and is heat-treated by maintaining the optical fiber within a heated treatment zone for the total resident time of 0.07-0.25 sec, while subjecting the optical fiber to an average cooling rate of 1,200-5,000 °C/sec defined by ä[fiber surface temperature in an inlet zone]-[fiber surface temperature in the outlet zone]}/[the total resident time of the optical fiber in the treatment zone] (block 20).

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing a thin glass soot sheet which can be taken up and a sintered glass sheet.SOLUTION: Glass soot particles generated from a burner array 105 are deposited on a curved depositional surface 103 of a rotary drum to form a glass soot layer. Then, the glass soot layer is exfoliated from the curved depositional surface 103 to obtain a soot sheet. The soot sheet can be changed into solidified glass by being sintered. The soot sheet and the solidified glass can become sufficiently long and flexible so as to be changed into a roll 117 by being taken up.

Abstract: PROBLEM TO BE SOLVED: To manufacture a dispersion compensation fiber with high negative dispersion value and a large effective area. SOLUTION: A preform to be stretched having a core glass region and a surrounding clad layer is formed and stretched by >=100 g stretching into a waveguide fiber having 125 to 170 μm outer diameter. The waveguide fiber is coated with at least one layer of a polymer material. The coated waveguide fiber is heat treated to substantially remove the residual stress in the coating. The core glass region consists of at least three segments and the surrounding clad layer surrounds the core glass region and has the refractive index nc lower than that of at least a part of the core glass region. The radii r1 and ri and relative refractive index percentages Δ1% and Δi% are selected so as to show negative total dispersion
