Abstract
An optoelectronic module has a laser diode configured on a substrate. The laser diode is drivable using an electronic drive device. At least one electrode of the laser diode is connected or coupled to the substrate. In order to match the impedance of the laser diode to the assigned electronic drive device, the substrate is designed as an electric line coupled to one electrode of the laser diode, and the impedance is matched by setting the specific electric conduction properties of the substrate. In this way, in addition to the mechanical function as carrier of the laser diode and the thermal function of dissipating the heat produced in the laser diode, the substrate additionally fulfills an electric function of impedance matching between the laser diode and the assigned electronic drive system. The optoelectronic module therefore offers improved EMC properties.
