| 81 | Method of making graded refractive index fibers and rods | US17986 | 1979-03-07 | US4246016A | 1981-01-20 | Walter P. Siegmund |
| 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. | ||||||

| A hydrolyzing flame technique is used to build up glass soots of at least two different compositions upon a rotating starting member. The process is repeated until the soots define at least one helically-oriented body of soot of one composition completely enveloped by a soot of a second composition. The soot-covered starting member is then subjected to heat to fuse it whereupon the soots are fused into compositions exhibiting different indices of refraction. The member can then be drawn into a elongate structure comprising an optical waveguide extending helically through the body of the structure. | ||||||
