ABSTRACT:
In silicon micro mechanical units, a coupling arrangement for optically coupling a fiber to a planar optical waveguide integrated on a substrate. The coupling arrangement provides a fiber arranged in a V-shaped groove of the substrate, leading to the planar waveguide and terminating in a low-attenuation butt coupling between the fiber and the planar optical waveguide. The butt coupling achieves the low-attenuation without great outlay, and cost-beneficially. A further embodiment employs welding the fiber to the waveguide.
