This thesis deals with optical signal processing of high-speed optical data signals at 160-640 Gbit/s. By exploiting non-linear effects in optical fibres several signal processing functionalities are implemented. This includes wavelength conversion of intensity modulated and phase modulated data signals, conversion between intensity and phase modulation, clock recovery for synchronising a receiver to an incoming data signal and finally reduction of timing sensitivity in such high-speed systems.
