Abstract
An apparatus for facilitating the alignment of an optical fiber to an integrated waveguide component comprising a substrate having an integral waveguide comprises a mask arranged to be disposed between the optical fiber 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 fiber to be transmitted to the waveguide but to substantially prevent light from the optical fiber from passing around the waveguide and/or through the substrate.
