Abstract
A horizontal deflecting optical waveguide is formed in an integrated circuit-like structure having a substrate and at least one layer of dielectric material above the substrate. A trench is formed in the dielectric material, and the trench has first and second portions angularly joined at a bent portion. A reflective layer of material adjoins, conforms to and extends along the side walls of the trench. A core of optically transmissive material conforms to the reflective layer within the trench. The reflective layer forms a wall at the bent portion which reflects light from the core located in one portion into the core located in the other portion.
