            Abstract : 
The high-speed amplitude limiting performance of a saturated fibre-optic parametric amplifier is numerically studied. It is shown that walk-off between the pump and signal pulses caused by a large dispersion slope makes the saturation behaviour less efficient and induces interaction between neighbouring signal pulses mediated by temporally-broadened pump depletion, both of which degrade the limiter performance.
