  • An Optical Waveguide Comprising A Core Region With Integrated Hologram
    Publication number: 20150369985
    Abstract: An optical waveguide comprising an axial direction and a cross-section perpendicular to said axial direction is shown. The optical waveguide comprises a core region. The core region includes an integrally formed hologram, which extends along a first axial segment of the optical waveguide, the first axial segment having a first axial length. The hologram, seen in the cross-section, includes a micro-structure with written elements having a modified refractive index different from areas of the core region with an unmodified refractive index.
