Abstract: A single mode optical waveguide is fabricated in a manner such that the core thereof is subjected to a stress-induced birefringence. This characteristic is accomplished by introducing into the cladding region of the fiber on opposite sides of the core longitudinally extending regions of glass having a thermal coefficient of expansion different from that of the remainder of the cladding. A number of novel techniques are disclosed for forming such a fiber.

Abstract: A process for preparing a glass rod having a graded refractive index for use as the start rod in the production of optical waveguides is disclosed. The process comprises depositing and sintering borosilicate particles on a glass rod to form a rod having a larger diameter than the original fused silica rod and drawing this rod to obtain a start rod having the same diameter as the original glass rod but exhibiting a partially radially graded refractive index. Optical waveguides prepared from such graded start rods have a more uniformly graded radial index of refraction profile.

Abstract: The present invention relates to a new glass material applicable in those situations where thermal and/or mechanical shock would limit the use of other glass materials presently available. Dopants are deposited into the interconnected pores of a porous glass in a non-uniform manner such that upon consolidation and cooling the final article has its surface under compressive stress. Dopants may also be added to control color and other appearance features. A porous silicate glass is washed with sodium hydroxide followed by immersing the washed glass in a liquid solution of a dopant in a liquid solvent therefor to stuff the pores of the washed glass with the solution. Thereafter, the solvent is removed from the pores and the pores are collapsed by a heating step.

Abstract: A glass optical waveguide filament preform is prepared by chemical reaction of vapor ingredients within a glass bait tube. As the reactants flow through the bait tube, a hot zone traverses the tube to cause the deposition of sooty reaction products in the region immediately downstream of the hot zone. A baffle tube extends into that end of the bait tube into which the reactants flow. The baffle tube, which traverses the bait tube along with the burner, ends just short of the hot zone so that no soot is deposited thereon. A gas flowing from the baffle tube creates a gaseous mandrel which confines the flow of reactant vapors to an annular channel adjacent the bait tube wall in the hot zone, thereby increasing deposition rate and efficiency.

Abstract: A method of making solid glass articles by the flame hydrolysis technique. First and second layers of glass soot produced by a flame hydrolysis are deposited on the outside surface of a mandrel to form a porous preform. The refractive index of the soot particles of the first layer is greater than that of the soot of the second layer, and the soot of the first layer has a viscosity lower than that of the second layer. The mandrel is removed, and the soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank. The glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process. The resultant blank may be heated and drawn into a filament, or it may be sliced into optical windows, lenses or the like.CROSS-REFERENCE TO RELATED APPLICATIONThis is a continuation of application Ser.

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: Two gaseous raw glass materials containing dopants to provide different refractive indices and borne by an argon carrier are jetted from the central or inner and first concentric nozzles 11, 12 of a five tip burner 1; an argon shield is supplied through the second concentric nozzle 13, and hydrogen and oxygen are supplied through the third and fourth concentric nozzles 14, 15, respectively. Soot-like glass particles 4 are formed by flame hydrolysis and deposited on the lower end of a start rod 3 which is gradually rotated and withdrawn to thus grow a cylindrical preform 2. The intermixing of the particles formed from the two glass materials produces a preform having a substantially parabolic radial index of refraction distribution, which characteristic is retained in an optical communication fiber formed by sintering and drawing the preform.

Abstract: A refractory starting member is rotated and, at the same time, moved along the axis of rotation. A glass raw material for the formation of the core of a porous preform and consequently an optical fiber preform is introduced into a high temperature portion near the tip of a high temperature burner from a nozzle for the core disposed in alignment with the center of rotation of one end face of the starting member. The glass raw material blown out from the nozzle for the core are caused by the flames of the high temperature burner to react to produce glass fine particles, which are deposited on abovesaid end face of the starting member at the central portion thereof in its axial direction to form a porous core. At least one nozzle for spraying a glass raw material for the formation of the cladding of the optical fiber preform is disposed opposite to the end face of the starting member but a little deviated from the axis of rotation thereof, or disposed opposite to the peripheral surface of the porous core. The glass raw material for the cladding is sprayed from the nozzle for the cladding to the high temperature portion of the high temperature burner, and caused to react to form glass fine particles, which are deposited on the end face of the starting member on the outside of the porous core or on the peripheral surface thereof at the same time as the formation of the latter, forming a porous cladding. The porous preform thus obtained is moved into a high temperature furnace provided on the path of movement of the preform for the vitrification thereof into an optical fiber preform.
