Abstract
In this paper, we propose and theoretically demonstrate two-input arbitrary Boolean logic gates using single semiconductor optical amplifier (SOA) and optical filtering at 10Gb/s. The system consists of an SOA and a specialdesigned optical filter. Before the SOA, there are two input data signals and a probe signal. The data signals should be ultrashort pulse sequence. Because different input power can cause different frequency shifts of the probe signal, different logic gates can be obtained by different filter detuning. Assisted by single Gaussian optical filter, we obtained logic NOR, OR, AND, XOR. Assisted by special filter with double peaks, we obtained logic XNOR and NAND. All the logic gates are obtained by changing the consequent filter only. The bit error rate (BER) measurement is analyzed for all logic gates. Our scheme is quite simple and robust for multifunctional logic gates. These logic gates can be used to the advanced complex logic circuits.
