    Abstract: A method of creating a codoped layer (18) includes creating a first layer (14) having a first dopant and at least one other layer (16) have another dopant, then interdiffusing the dopant to create a substantially homogeneous codoped layer. More than one dopant may be deposited in a single layer. The creating conditions may be optimized for each layer (14, 16). Further, when the creation of a layer includes sequential deposition and consolidation, conditions for each process may be optimized within the layer creation. While at least two layers (14, 16) are formed, the interdiffusion substantially eliminates any stratification or layer structure.

    Abstract: An optical fiber (10) made with a central core (12), a first cladding layer (16), and a second cladding layer (18) having a series of perturbations or irregularities formed into the otherwise generally circular outer boundary of the first cladding layer (16). The irregularities in the first cladding layer (16) interrupt the propagation of skew rays and encourage coupling into the core (12). An intermediate cladding (14) may be provided between core and first cladding layer (16). A method of fabricatiNG the optical fiber is also disclosed, comprising, drilling a plurality of holes within the first cladding forming material and at the boundary thereof with the material forming the second cladding layer, drilling a central hole and inserting a preform core rod into said central hole. Drawing integrates the rod and drilled rod and the plurality of holes are collaped, so forming an irregular, quasi-circular boundary between first and second cladding forming layers in the drawn fiber.

    Abstract: This process provides a new way to embed rare earth fluorides into silica (or germania-doped silica) glasses by solution chemistry. Embedding rare earth fluorides into a silica (or germania-doped silica) glasses comprises the following steps. The first step forms a porous silica core preform by OVD process. The second step submerges the preform into an aqueous solution of rare earth ions. The third step removes the preform from the solution and washes the outside surfaces of the preform. The fourth step submerges the preform into an aqueous solution of a fluorinating agent, such as ammonium bifluoride, HF or KF. Rare earth trifluorides precipitate out from the solution and deposit on the wall of pores. This is followed by drying.

    Abstract: The present invention is directed to a method and apparatus for forming soot used in making glass, and in particular, optical waveguides. A liquid precursor (66) is first fed into orifice (52) of a liquid orifice insert (48) within an injector (44) positioned within an atomizing burner assembly, and is thereafter discharged from the injector into a pressurization chamber (56). An atomization gas (70) is also fed into the pressurization chamber (56) to mix with the liquid precursor liquid stream (68) which breaks into droplets (76). The liquid precursor and atomization gas are forced under pressure out of an atomization orifice (32) on the face of the burner (30) assembly. Flame gas (74), reaction gas (84) and shield gas (82) are ejected from burner orifices (40, 38, 36 and 34) to produce the flame. The atomized liquid precursor thus discharged is fed into the flame (72) produced at the face of the burner assembly where the atomized liquid precursor reacts with the flame to form soot (78) on a rotating mandrel (80).

    Abstract: An optical fiber waveguide resistant to ionizing radiation having a glass core of predetermined refractive index surrounded by glass cladding having a lower predetermined refractive index. The glass core and glass cladding are each composed of high purity silica incorporating gallium as a constituent. The gallium is present in the form of Ga2O3 in a concentration of about 0.01 to .15 mole percent ratio to the silica. The glass of the optical waveguide can further include phosphorus in the form of P2O5 as an additional constituent in the amount of from about 5 to 16 mole percent ratio to the total amount of all constituents. The waveguide of the invention is preferably manufactured by using GaCl3 in combination with an internal vapor phase process to produce a silica soot (16) containing Ga2O3 on the interior surface of a high purity silica tube (10). The soot is then consolidated and the tube collapsed to form a substantially voidless solid rod preform of high purity SiO2 containing Ga2O3. The process of manufacture is controlled so as to disposed Ga2O3 within the preform in a concentration of about .01 to .15 mole percent ratio to the total constituents of the silica preform. The process can further include the deposition of P2O5 within the preform.
