Abstract
The invention relates to a device for regenerating optical signals by intensity modulation and phase modulation of the optical signals, said device including:a mode locking laser for recovering a clock signal representing the clock of the bits of the optical signals to be regenerated, anda modulation interferometer structure having a first interferometer arm and a second interferometer arm, enabling amplitude modulation and phase modulation of optical signals by said clock signal, and including a semiconductor amplifier in the first interferometer arm. The mode locking laser is coupled to said first interferometer arm so that said amplifier of the first interferometer arm is a common component of the mode locking laser and said interferometer structure.
