ABSTRACT:
Optoelectronic circuit in a semiconductor component having a branching waveguide. A respective optical amplifier constructed as a diode is integrated in each branch of this waveguide and the doping of the materials surrounding the active layer of these diodes is selected such that each diode can also be separately operated as a photodetector without transverse currents arising between the diodes.
