    摘要: A singlemode lightwaveguide-coupling element is positioned between an initial waveguide section which there has a basic final width (W0f) and a final waveguide section which there has a basic initial width (Wn+1i) which is bigger than the basic final width (W0f). The lightwave directions of both waveguide sections are inclined at a predetermined total angle (&Dgr;&agr;) towards each other. Starting from the initial waveguide section, the lightwaveguide element comprises intermediate waveguide sections each of which at its end has a lightwave direction which is inclined towards the lightwave direction at its opposite end at an inclination angle (&Dgr;&agr;v), such that the sum of all inclination angles equals the predetermined total angle (&Dgr;&agr;).

    摘要: An optical coupling device for coupling light with an optical waveguide comprises a mirror formed within an optical waveguide. The mirror comprises a first material, a first reflective end, and a second reflective end. The first material is light conducting and has a first refractive index. The first and second reflective ends reflect and transmit light. The mirror has an axis line. The optical coupling device is useful for extracting light from a waveguide and providing a backlight for a liquid crystal display.
