    Abstract: A system and a method in producing a doped glass material, particularly a glass material to be used in light amplifying optical waveguides. The method comprising: bringing at least a first dopant and a second dopant of the glass material into a vaporous gas phase; controlling the vapour pressure of the gas phase of each dopant by bringing each dopant to a desired temperature which is simultaneously used to control the composition of their gas phase; and mixing each vaporous dopant with the gas flow of the basic material for the glass material, which basic material is also in a gas phase and is used as a carrier gas for the dopants, wherein said basic material and said dopants together constitute the required gas flow of so-called reactants, to be used for producing the glass material; performing the mixing so that said dopants are each mixed in turn with the same gas flow of the basic material in such an order that said desired temperatures of the dopants are increasing in relation to one another.

    Abstract: An improved method of forming an optical fiber preform includes separately forming a rod-like inner member and a hollow tube-like outer member by a soot glass deposition technique. The inner member is inserted into the outer member, while they are both in their unconsolidated state, and the asssembled parts heated to cause the outer member to collapse about the inner member and form a preform. The resulting preform can be drawn in one or more stages to provide an optical fiber having sharp step change in its index of refraction between the core and the cladding, a superior quality core to cladding interface, and improved optical transmission qualities. The inner and outer members can, if desired, be partially consolidated but for an unconsolidated layer at their interface prior to heating the outer member to cause it to join with the inner member. In accordance with one feature of the present invention, an unconsolidated layer can be left on the outside surface of the outer member to provide a resulting fiber having superior mechanical handling characteristics.

    Abstract: Hydroxyl free deposition with high efficiency and at a high deposition rate may be achieved, even with use of relatively inexpensive raw materials, by utilizing a ring-shaped plasma activated axial chemical vapor deposition obtaining 100% chemical conversion and fractional volatilization of impurities. The plasma is induced in an annular stream of a plasma-forming gaseous medium, and the reactant or reactants used in the axial chemical vapor deposition are introduced into the center of the ring-shaped plasma to be converted by the heat of the plasma flame into soot which is deposited on a bait. An annular stream of a cooling medium flows outwardly past the plasma flame and is circumferentially centered by an extension of the outer tubular element of a plasma torch in which the plasma is generated. An RF generator which induces the plasma is operated at a frequency exceeding 20 MHz to give the plasma flame the desired ring-sloped configuration.

    Abstract: A method for producing an optical fiber comprises (i) the step of depositing a barrier layer on the inner wall surface of a glass tube by the CVD (chemical vapor deposition) process, said barrier layer being capable of preventing the diffusion of impurities and being made of high-silica glass which has a refractive index that is substantially equal to that of the glass tube and which contains at least one substance for lowering the refractive index of silica and at least one substance for raising the refractive index of silica, (ii) the step of depositing a glass film of desired refractive index on the barrier layer by the CVD process, (iii) the step of heating and collapsing the resultant glass tube into a composite rod or the so-called optical fiber preform, and (iv) the step of heating and drawing said optical fiber preform into the optical fiber, whereby the optical fiber which has the impurity diffusion-preventing layer between the core and the outside glass layer can be easily produced.
