摘要： 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.
