The invention relates to a coupler in which the coupling between the waveguides is carried out on the one hand, by means of evanescent waves propagating in the medium separating these guides, and on the other hand by means of a non-linear interaction in the substrate, where the waveguides are produced. A first guide is produced by ion exchange of H+ ions and a second guide by local titanium diffusion in the substrate. |
