Abstract

In this paper, we propose a novel all-optical AND gate using frequency shift accompanied by cross-phase modulation in semiconductor optical amplifier. Theoretical model is built to analyze the performance of the proposed gate. Through numerical simulations, we find the bandwidth of the optical band filter can be optimized to improve the quality of the output signals. The AND gate with short pulse-width and high energy of the control signals is adaptive to high-speed optical packet-switched and label-switched network.
