Abstract

PURPOSE:To achieve the higher density of a deposited film and suppress the decrease in refractive index at the central portion of an optical fiber by heating a hollow glass tube while flowing a specified gas within the glass tube prior to heating and fusing of the glass tube in vapor phase chemical reaction.
