A reconfigurable all-optical logic gates with not-inverted data technique is demonstrated by using a single semiconductor optical amplifier (SOA) and a tunable optical band-pass filter (TOBPF). Based on cross-gain modulation (XGM) and four-wave mixing (FWM) in the SOA, multiple Boolean calculation of the return-to-zero signal is realized, and different logical functions are switched by adjusting band-pass filter center wavelength and optical signal power. In the experiment, all-optical multiple logic gates of AND, NOT, NOR, NXOR,·B, and A·B functions at 10 Gb/s are demonstrated without changing the experimental setup. In order to obtain not-inverted RZ data, the clock signal is used for the probe signal which is benefit to combining the basic logics to complicated logic gates.
