摘要：A method of forming a preform which has a glass core surrounded by an outerglass cladding with a coating of an particulate optically active material disposed betweenthe core and cladding. The method includes providing a glass core having a viscositywhich lies within a given preselected temperature range, followed by forming a coherentcoating of an optically active particulate material over the surface of the core, with thecoating material having a viscosity which is equal to or less than the viscosity of the glasscore. A glass cladding is formed over the coated layer, with the cladding glass having aviscosity which overlaps the viscosity of the core glass. The optically active material is aninorganic material which includes a metal, metal alloy, ferrite, magnetic material and asemiconductor. The invention includes the product formed by the process.
