Abstract

A branching element for a single mode light waveguide characterized by monomode guides extending from a semi-transmissive reflective layer that is inclined to the axis thereof and the branching light waveguide is a multimode light waveguide which is positioned to receive light reflected by the layer from one of the monomode guides. The device has a good coupling efficiency and can be manufactured by a cheap and simple process.
