Abstract:
A method of making an optical device comprising a substrate on which are integrated a layered optical waveguide structure comprising a polymeric core layer sandwiched between two deflection layers of a lower refractive index than the core layer, and optical fibre ends, the optical fibre ends being positioned in grooves, the method comprising the following steps:providing a flat substrate with a layer that on releasable upon proper treatment;applying a first polymeric deflection layer on the releasable layer;applying a core layer polymer on the first polymeric deflection layer;applying a second polymeric deflection layer on the core layer;treating the releasable layer in such a way as to release the layered waveguide structure from the flat substrate;placing the released layered waveguide structure on the substrate comprising grooves;providing the layered waveguide structure with a facet adjacent to the grooves;providing waveguide channels in the layered waveguide structure by suitably irradiating the care layer, the channels being positioned so as to be aligned with the grooves; andplacing fibre-ends in the grooves.
