Abstract
The method of fabricating alumina-doped silica fibers allows the production of silica and dopant with reactions between gaseous chemical compounds. Alumina is obtained from a reaction between oxygen and a low-temperature vaporizable organometallic compound. The optical fibers produced do not present the refraction-index dip and exhibit low attenuation.
