%X All-optical XNOR and AND logic gates using four-wave mixing (FWM) and cross-gain modulation (XGM) in a single semiconductor optical amplifier (SOA) with improved dynamics are simultaneously realized. By numerical simulation, the effects of the input optical wave powers and injection current on the critical factors of the logic gate performances, such as the ON--OFF contrast ratio, the power-output level of the logic `1', and the difference between power outputs of the logic `1', are investigated in detail. In addition, the effect of the counter-propagating CW pump on the gain recovery is analysed.
