Abstract: Transmitter module for optical interconnections, comprising a metal container housing an optical emitting device, an integrated circuit containing the driving circuit of the emitting device and an optical fibre extending outside the container, the emitting device being mounted on a metallic ground area realized on the integrated circuit. The cathode is electrically connected to the ground area and the anode is connected to a second metal area, connected with the output of the driving circuit. The module uses a type of assembly which minimises problems due to the length of the connecting wires, to parasitic effects and to the effects of signal reflections due to impedance mismatching. It also requires reduced power for its operation and it is provided with a structure facilitating dissipation.

Abstract: A high speed drive circuit for optical sources. The circuit comprises bias and modulation current generators for both p-type and n-type optical sources, and a pair of control voltage sources for controlling the bias and modulation current generators, which obtain pairs of control voltages from an adjustable driving current. The circuit includes control logic and CMOS gates for selecting between the p-type and n-type generators by means of an external signal. The circuit is fabricated as an integrated circuit having three pads, one for each control voltage source and the third pad comprises the current generators, the CMOS gates and the control logic circuit.

Abstract: In the fibre and in any fibre (F), a reflecting surface (F1) is created that is generically tilted with respect to the main propagation path (T1) of the optical radiation in said fibre, so as to originate by reflection an additional propagation path (T2) that is generically deflected with respect to said main propagation path (T1). In a mounting support (2) common to the fibre (F) and the related opto-electronic component (O), a groove is made along an external face (2a) so as to accommodate the optical fibre (F) in a tight condition. The groove (3) is then covered through a laminar cover, that is transparent to the radiation and has a flat surface (4a). The fibre (F) is inserted into said groove in order that said deflected propagation path (T2) passes through said cover (4) of material transparent to the radiation, and the opto-electronic component (O) is mounted on said cover (4) in alignment with said deflected propagation path (T2).

Abstract: The circuit comprises bias and modulation current generators (T1...T6) for both p-type and n-type optical sources, and a pair of sources of control voltages (B, M) for the bias and modulation current generators, which obtain pairs of control voltages from an adjustable driving current. An external signal allows selecting, by means of a control logic (LC) and CMOS gates (P1...P6), the generators required by the source (LA). The circuit is made by using three pads of an integrated circuit, one for each control voltage source (B, M) and the third (D) comprising the current generators (T1...T6), the CMOS gates (P1...P6) and the control logic (LC).
