Abstract: A glass layer is formed inside a silica glass tube and another glass layer having a refractive index higher than that of the abovementioned glass layer is formed on said glass layer. After these glass layers are formed, one end of the glass tube is collapsed. While the internal pressure of the glass tube is being reduced below the atmospheric pressure, the glass tube is caused to collapse by heating, thereby yielding a preform for an optical fiber. The optical fiber produced from this preform has the difference in the refractive indices of the two orthogonal major axes of at least 1.6.times.10.sup.-4 and maintains the linear polarization plane.

Abstract: An optical fiber waveguide of the type comprising an outer cladding layer, an axially disposed core of SiO.sub.2 doped with GeO.sub.2 and a first inner cladding layer of SiO.sub.2 doped with an oxide such as P.sub.2 O.sub.5 for lowering the preform processing temperature. A second inner cladding layer of pure SiO.sub.2 is disposed between the first inner cladding layer and the core to prevent P.sub.2 O.sub.5 from diffusing into the core, thereby eliminating absorption losses from the P--O--H band in the 1.1-1.8 .mu.m region.

Abstract: A process for producing an optical transmission fiber is provided which comprises feeding highly pure halides, hydrides or organic compounds of Si and B by way of carrier gas on the outer surface of a fused silica rod or a fused silica pipe, or inner surface of a fused silica pipe, oxidizing them and depositing the products to form a pure fused silica layer or a doped fused silica layer containing B.sub.2 O.sub.3, melting the pipe and the deposited layer followed by a spinning. The SiO.sub.2 layer can alternatively contain fluorine instead of B.sub.2 O.sub.3. A further SiO.sub.2 layer can be deposited thereon to improve the spinning processability and lower the index of refraction of the B.sub.2 O.sub.3 containing layer.

Abstract: The invention provides a method for preparing a preform for producing by drawing an optical waveguide comprising a core region and a sheath region whose refractive index varies in the radial direction, so that the index of the former is greater than those of the second. The method consists in starting from a bar of a first composition for forming the core region and in forming, by means of a plasma torch, on its surface, a deposit of a plurality of layers whose composition varies in the radial direction, is characterized in that glass powder is fed to said torch transversely to the jet of said torch; in that said bar is drawn after each layer is deposited to bring its diameter to a value close or equal to the initial diameter; and in that the chemical composition of the glass powder is changed after each layer is deposited. The preform obtained by the present method makes it possible to produce by drawing optical waveguides for applications in the field of information transmission.

Abstract: A method of making glass optical waveguides by the flame hydrolysis technique. Particles of glass soot produced by flame hydrolysis are deposited on the outside surface of a mandrel to form a porous preform. The soot particles closer to the mandrel have a refractive index greater than that of the soot disposed toward the outer surface of the preform. The mandrel is removed and the resultant hollow soot preform is supported in a draw furnace through which a helium-rich gas flows. The preform is heated to a temperature sufficient to cause said soot to consolidate and simultaneously permit an optical waveguide filament to be drawn therefrom.
