Abstract

Semiconductor optical amplifier (SOA)-based all-optical XNOR and AND gates using four-wave mixing (FWM) and cross-gain modulation (XGM) with improved dynamics are simultaneously realized. 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 output power level of the logic "1", and the output power difference of the logic "1", are theoretically investigated in detail. In addition, the effect of the counter-propagating CW pump on the gain recovery is analyzed.
