【発明の名称】光集束性フアイバ-導波管の製造方法
Document Type and Number:
Japanese Patent JPS604142
Kind Code:
B2
Abstract:
A method of forming an article such as a light focusing fiber waveguide by applying to a substantially cylindrical starting member a plurality of layers of material, each layer having a progressively lower index of refraction. The assembly so formed is heated and drawn to reduce the cross-sectional area to form a fiber having a stepped radially varying composition. Alternatively, a plurality of layers of material, each having a progressively higher index of refraction are applied to the inner surface of a tubular member. The resulting substantially cylindrical hollow assembly is heated and drawn to reduce the cross-sectional area and to collapse the remaining inner hole to form a fiber having a solid cross-sectional area with a stepped radially varying composition.
