Abstract

An optoelectronic device that includes at least one adjustable optical damping member arranged upstream of a photodetector and damps the optical radiation passing to the photodetector. The device is configured so that an electrical output of an amplifier is connected directly or indirectly to the adjustable optical damping member. An output signal of the amplifier or a control signal formed therewith drives the optical damping member, and the photodetector, the amplifier and the damping member are integrated in the same semiconductor substrate.
