Abstract
PURPOSE:To stably produce high quality optical fiber using high yield glass by sticking high viscosity glass formed by plasma oxidation of raw gases to the inner walls of heat resistant reactors; lowering the viscosity by heating; and letting the resulting low viscosity glass flow out of the reactor bottoms. CONSTITUTION:Inner reactor 1 and outer reactor 2 are evacuated to, e.g. 10 Torr from lower funnel-shaped outflow holes 1a,2a. POCl3, GaCl3 and GeCl4 stored in separate vapor phase generators are supported on inert gas such as Ar, mixed with O2, and fed 4 into reactor 1. SiCl4, BBr3, POCl3 and GaCl3 are fed 5 into reactor 2 together with O2 gas by the entirely same method. Next microwave oscillation coils 3 are actuated to stick P2O5-Ga2O3-SiO2-B2O3 four component glass layers 7,8 of high viscosity to the inner walls of reactors 1,2 by plasma oxidation. The whole reactors are shifted into an electric furnace for spinning, and by controlling heating furnace 6 the viscosity is lowered. The resulting low viscosity glass is spun to produce optical fiber.
