An optoelectronic surface-mounted device is provided comprising a premolded casing having a first cavity and a second cavity and a leadframe to which a first electrooptical element and a second electrooptical element are mounted. The leadframe is embedded in the premolded casing. The first cavity is adapted for providing a first electromagnetic radiation path between a first waveguide and the first electrooptical element, wherein the second cavity is adapted for providing a second electromagnetic radiation path between a second waveguide and the second electrooptical element. The first cavity and the second cavity are formed in the premolded casing to decouple electromagnetic radiation propagating along the first electromagnetic radiation path from electromagnetic radiation propagating along the second electromagnetic radiation path.

Various embodiments of arrangements for optically coupling an optical waveguide to an optical unit of an optical module are provided. One embodiment is an optical module for optically coupling an optical waveguide to an optical unit. One such optical module comprises: a reference structure having a reference geometry that defines a first axis of symmetry; an optical unit having an optical axis along which light is transmitted or received, the optical unit positioned relative to the reference structure with an offset between the first axis of symmetry and the optical axis; and a coupling element that couples the optical unit to an optical waveguide, the coupling element having an eccentric hole which functions as a fiber guide and a structural geometry adapted to compensate for the offset between the first axis of symmetry and the optical axis.
