More Information
Summary:The invention relates to a component (10) with a photodetector (PD) and an electrical amplifier (TIA) connected to the photodetector (PD), wherein the photodetector (PD) and the amplifier (TIA) are integrated in the same semiconductor substrate (11). According to the invention, at least one adjustable optical damping member (30) is arranged in front of the photodetector (PD), which damping member damps or at least can damp optical radiation arriving at the photodetector (PD), an electrical output (A) of the amplifier (TIA) is connected directly or indirectly to the adjustable optical damping member (30) and an output signal (AS) of the amplifier (TIA) or a control signal (ST) formed therewith controls the optical damping member (30), and the photodetector (PD), the amplifier (TIA) and the damping member (30) are integrated in the same semiconductor substrate (11).
