New Ways to Obtain Optical Fibers with a Refractive-Reflective Cladding from Glass with Any Composition

Abstract

A method of obtaining optical fiber with a refractive-reflective cladding formed in the process of extrusion from a single-spinneret vessel as a result of the interaction between the spinneret material and the glass melt of the light-guiding fiber core. Using glass with highly volatile components for the light-guiding core in order to best match the compositions of the initial glass and the light-guiding core the method affords the creation of a polycrystalline or glassy layer with the same composition along the surface during the extrusion process.
