Abstract

PURPOSE:To obtain the titled base material with low loss and low dispersion over a wide wavelength region by forming a porous glass layer contg. fluorine for the 1st clad and a porous glass layer for the 2nd clad around a porous glass body for a core and converting them into transparent glass by heating. CONSTITUTION:SiCl2 and GeCl4 are fed into a torch 1 for synthesizing fine glass particles for a core together with a carrier gas such as He, SiCl2, POCl3 and SF6 are fed into a torch 2 for synthesizing fine glass particles for the 1st clad together with a carrier gas, and SiCl4 is fed into a torch 3 for synthesizing fine glass particles for the 2nd clad together with a carrier gas. They are subjected to flame hydrolysis to form fine glass particles, and a porous glass body is grown from the particles. The body is then heated to 1,500 deg.C in an atmosphere of He and Cl2 and coverted into transparent glass by dehydration. Thus, a base material for an optical fiber with a Q type refractive index distribution can be manufactured, and this optical fiber has the advantage of low-dispersion transmission in a wide wavelength region.
