The present invention relates to a method and a device for manufacturing a waveguide pattern in a waveguide connector. The waveguide connector comprising a topographic pattern is placed over a transparent polymeric multilayer laminate arranged on a rigid foundation, where at least one layer consist of a core and at least two other layers are formed of a cladding material, said cladding material surrounding said core layer, each on one side, and the cladding material having a lower refractive index than the core material. The waveguide connector is pressed towards the polymeric multilayer laminate so that the topographic pattern in the waveguide connector stands out in relief in the laminate to form the waveguide pattern in the waveguide connector and where the multilayer laminate is fixed in the waveguide connector after pressing.
