    Abstract: The invention relates to a method for economically producing a quartz glass rod consisting of synthetic quartz glass with a radially and axially homogenous refractive index curve. According to the invention, a whole cylinder consisting of quartz glass is coated with a coating tube consisting of porous glass, the latter shrinking onto the whole cylinder during sintering. The coating tube has a predetermined refractive index which ensures that there is a maximum increase in the refractive index value of 0.001 in the area of a contact surface between the whole cylinder and the shrank-on coating cylinder. A solid quartz glass rod produced in this way is characterized by a homogenous refractive index distribution in an axial and radial direction and comprises a whole cylinder consisting of synthetic quartz glass which is encased in a quartz glass layer formed by a coating tube consisting of porous quartz glass that is sintered and shrunk on with a maximum increase in the refractive index of 0.001 in the area of a contact surface. The inventive quartz glass rod is used for economically producing a preform for multimode fiber optical waveguides.

    Abstract: The invention includes methods of making lithography photomask blanks. The invention also includes lithography photomask blanks and preforms for producing lithography photomask. The method of making a lithography photomask blank includes providing a soot deposition surface, producing SiO2 soot particles and projecting the SiO2 soot particles toward the soot deposition surface. The method includes successively depositing layers of the SiO2 soot particle on the deposition surface to form a coherent SiO2 porous glass preform body comprised of successive layers of the SiO2 soot particles and dehydrating the coherent SiO2 glass preform body to remove OH from the preform body. The SiO2 is exposed to and reacted with a fluorine containing compound and consolidated into a nonporous silicon oxyfluoride glass body with parallel layers of striae. The method further includes forming the consolidated silicon oxyfluoride glass body into a photomask blank having a planar surface with the orientation of the striae layer parallel to the photomask blank planar surface.

    Abstract: A method for producing a preform capable of restricting deformation of each member during a production process, and a method for producing, using the preform, an optical fiber small in polarization mode dispersion. In the method for producing the preform, a collapse process is divided into at least two steps; a first step of forming a first collapse body by the collapse of a core rod member and a first clad tube member and a second step of forming a new collapse body by the collapse of the first collapse body and a second clad tube member. An obtained collapse body is drawn in at least the first step; and such a multi-stage collapse process and drawing of an obtained collapse body can reduce an outer diameter ratio of an outer-side member to an inner-side member to be collapsed and hardly produce deformation that would be caused by heating and the like at one time collapse.
