Abstract

An improved coupling element for coupling light into and out of a light component, which coupling element consists of a single core of cladded glass fiber whose cladding has a diameter that amounts to at least 1 mm so that the cladding acts as a member for supporting the core in the coupling element. Preferably, at least one flat surface is formed on the cladding to facilitate attaching the branching waveguide or fiber.
