ABSTRACT:
A process for the production of gradient fibers of glass by depositing layers of glasses having selected indices of refraction and then drawing fibers therefrom. The process is carried out by sequentially introducing a plurality of glass masses to form layers having progressively higher refractive index of refractions. The resulting layers are formed into an unitary body which is drawn into an optic fiber.
