Abstract:
An optoelectronic module comprising a substrate of semiconductor material with an upper surface, at least one optoelectronic component with a longitudinal direction and a passive waveguide being arranged on said upper surface, said component being fashioned in a layer sequence grown epitaxially on the substrate, said layer sequence being formed by layers selected from a group of layers of semiconductor material and layers of mixed crystal compositions of at least one semiconductor material, said passive waveguide being applied on the substrate as an integrated component part of the module and being arranged so that it couples radiation with a region of the optoelectronic component and couples radiation with an external terminal surface with the waveguide conducting radiation between said region and said terminal surface, said passive waveguide being formed by a constituent different from every semiconductor material in the optoelectronic component, at least one first contact being applied on an upper surface of the component facing away from the substrate and on a dielectric layer extending laterally with respect to the longitudinal direction of the component and at least one second contact being electrically connected to a lower layer of the component, said at least one second contact having a lower part arranged laterally with respect to the longitudinal direction of the component and a part applied on said dielectric layer.
