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.

Optoelectronic component including a photodetector and an optical damping member to damp the optical radiation passing to the photodetector

An optical signal modulator comprising a modulator unit, a photodetector and an electrical signal combiner. The modular unit having an optical ingress port for optical radiation, a first and second optical output port each for modulated optical radiation, and an electrical ingress port for an electrical modulation signal. The optical radiation is modulated in response to the electrical modulation signal. The photodetector is connected to the second optical output port and configured to measure the modulated optical radiation that is emitted, and to provide a monitor signal. The electrical signal combiner having a first input port for an external electrical data signal, a second electrical input port for a correction signal based on the monitor signal, and an electrical output port that is connected to the electrical ingress port. The combiner generates the electrical modulation signal by combining the external electrical data signal and the correction signal.

An optical module can include a beam steering portion and a first side defining an inner surface that faces the beam steering portion. The optical module can further include a second side that defines an inner surface adjacent to the inner surface of the first side. The inner surface of the second side can face the beam steering portion. The optical module can be configured to direct an initial light beam from the first side to the beam steering portion along a first direction. The optical module, and in particular the beam steering portion that can include a beam splitter, can divide the initial beam into a signal light beam and a fractional light beam.
