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 Ga.sub.2 O.sub.3 in a concentration of about 0.01 to 0.15 mole percent ratio to the silica. The glass of the optical waveguide can further include phosphorus in the form of P.sub.2 O.sub.5 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 GaCl.sub.3 in combination with an internal vapor phase process to produce a silica soot (16) containing Ga.sub.2 O.sub.3 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 SiO.sub.2 containing GeO.sub.2.The process of manufacture is controlled so as to dispose Ga.sub.2 O.sub.3 within the preform in a concentration of about 0.01 to 0.15 mole percent ratio to the total constituents of the silica preform. The process can further include the deposition of P.sub.2 O.sub.5 within the preform.

Abstract: A process for producing a glass product having .DELTA.n, the difference between the central and peripheral portions of the glass, greater than 0.04. This process utilizes a porous glass body which is produced via a phase separation technique. A dopant selected from the group consisting of (1) TlNO.sub.3, (2) TlNO.sub.3 and an alkali metal compound and (3) TlNO.sub.3, Pb(NO.sub.3).sub.2 and an alkali metal compound is then permeated into the micropores of the porous glass product. A concentration gradient of the dopant is then formed by leaching out a portion of the dopant from the micropores. After the dopant is solidified in the mircopores, the porous glass product is dried. A heat-treatment step then serves to collapse the micropores. A glass product having a gradient of refractive indices is therby obtained.

Abstract: Gradient refractive index fibers or rods are formed of leachable glass clad glass core preforms drawn to a desired diametral size, bundled together, fused under high compressing forces and rapidly interdiffused at a temperature above their deformation point. Cooling, annealing and separation of the fibers or rods by leaching provides the end product devices which may be cut into lengths required for the lens power desired and end polished. The refractive index gradient is produced by interdiffusion of T1.sup.+ and K.sup.+ ions between core and cladding glasses which are selected to contain substantial proportions of thallium oxide and potassium oxide respectively.
