Abstract
A method of manufacturing glass rod for optical waveguides is proposed. In this method, several gaseous mixtures or powdery mixtures of materials for glass forming are reacted at a high temperature and deposited on the top or end of a rotating glass rod which is initially deposited on a rotating base plate and grown in the form of a rod of a fixed powdery or vitreous state. It is possible to obtain the glass rod having a predetermined radial distribution of index of refraction.
