A novel ultra -wideband monocycle pulse generation method based on transfer curve of two Mach-Zehnder modulators (MZMs) is proposed. By changing the bias voltage of MZMs, positive and negative polarity monocycle pulse s are generated.
The authors have proposed, simulated, and experimentally demonstrated all-optical multiple logic gates using two parallel semiconductor optical amplifier (SOA)-Mach-Zehnder interferometer (MZI) structures that enable simultaneous operations of various logic functions of XOR, NOR, OR, and NAND. The proposed scheme, which is optimized by adjusting the optical gain and phase differences in SOA-MZI structures...
