An optical component 9 such as a photodiodereceiver or a laser transmitter is mounted on a ceramic file 15 at right angles to a closely adjacent circuit board (substrate) 16 which carries an electrical circuit 17. The circuit board 16 has an electrically conductive track 18 extending to an edge of the board 16 adjacent to an edge of the tile 15. The edge surface of the tile 15 has a localised recess (12, Fig 3) carrying an electrically conductive material 10 which extends across the thickness of the tile and along a major surface of the tile 15 to connect with the optical component 9. A short bondwire 21 is provided which links the electrically conductive material in the recess (12) to the adjacent electrically conductive track 18 on the circuit board 16. An optical fibre 27 is closely coupled to the component 9. |
