In future optical communication networks, all-optical signal processing will play an important role. For example, signal transmission in a complex fibre network with many switching nodes requires the development of wavelength converters, optical regenerators etc.. There are very few publications where a complete all-optical regeneration, containing clocked decision as well as clock recovery has been performed. On the other hand there are many contributions on signal regeneration without clock recovery or with electronic clock recovery and also on all-optical clock recovery. One difficulty here is to achieve the compatibility between the all-optically created clock signal and the all optical decision element. In this contribution, we perform a complete all-optical signal regeneration (reamplification, retiming, reshaping) using semiconductor laser components. We achieve polarization and wavelength independent operation at the input and wavelength tuning of the regenerated data signal either to the same wavelength as the input data signal or to a wavelength differing up to 35 nm.
