Abstract
A glass fiber for use as a light waveguide characterized by a one piece member having at least one transverse opening extending through the fiber to subdivide a section of the fiber into two portions connected at each end by the zones of the fiber free of the opening. By cutting in the area of the opening, a branch fiber can be produced. Preferably, the fiber includes a pair of cores which are separated by the openings. The method includes drawing the fiber from a mass of softened glass and while in the softened state, forming the openings therein or by drawing the fiber from a preform having at least one transverse extending opening. Preferably the preform is formed by joining two members having flat surfaces together and the openings in the preform are formed by forming transverse grooves in one of the flat surfaces.
