| 摘要 |
An apparatus for facilitating the alignment of an optical fibre to an integrated waveguide component comprising a substrate having an integral waveguide comprises a mask arranged to be disposed between the optical fibre and the integrated waveguide component, wherein the mask includes an aperture extending therethrough. In use, the aperture is substantially exactly aligned with the waveguide thereby to permit light from the optical fibre to be transmitted to the waveguide but to substantially prevent light from the optical fibre from passing around the waveguide and/or through the substrate.
