It is shown that the resonant enhancements of the optical Kerr effect and the optical Stark effect of the same order are caused by the same change in the state of an atomic system. The analysis of the known experimental data demonstrates the identity of their influence on nonlinear optical processes. It is shown that a separate analysis of the influence of Stark shift and resonantly enhanced Kerr nonlinearities leads to incorrect results.

All-optical signal processing will be used in future communication networks. We discuss a new and generic scheme for such devices. The basic configuration comprises an asymmetric resonator within an active or passive nonlinear medium. This arrangement enables all-optical flip-flop operation and switching with a reduced threshold. In addition, a novel optical isolator concept based on resonator asymmetries is is introduced. The model is also applicable to photonic crystal based resonators.
