Resonator structures show great potential for improving ultrafast, nonlinear data processing and provide new functionalities - such as limiting and bistability - which cannot be realised with simple, homogeneous components. When operated in a pump-probe configuration, the signal processing possibilities are extended to multiple channels, however at the expense of a higher power level, which is related to the channel spacing. In this paper, all-optical phase shifting is discussed in the case of a pump-probe set-up and the advantages and disadvantages compared to a single signal approach are investigated.
