Laser diode assembly and device for operating a laser diode

A laser diode assembly, comprising:

• a semiconductor body containing a laser driver circuit configured to provide a bias current and a modulation current, wherein the laser driver circuit has a first surface formed at a surface of the semiconductor body and a second surface formed within the semiconductor body;
• a laser diode formed or arranged entirely on the surface of the semiconductor body in a monolithic manner, the laser diode comprising first and second connection contacts associated therewith;
• a coupling capacitance formed within the semiconductor body and defining first and second surfaces, wherein the first surface is coplanar with the surface of the semiconductor body and the second surface resides within the semiconductor body, the coupling capacitance further comprising first and second metallizations associated with the first and second surfaces, respectively;
• wherein the first connection contact of the laser diode is coupled to the first metallization of the coupling capacitance;
• and
• wherein the bias current is coupled to the first metallization of the coupling capacitance and the modulation current is coupled to the second metallization of the coupling capacitance.
