SHAO Yu-ting; LUO Bin; PAN Wei

With the aid of external optical injection,a novel all-optical logic gate based on Mach-Zehnder interferometer composed of semiconductor optical amplifier(SOA-M-ZI) was proposed.Meanwhile,by means of rate equations of the SOA,the logic AND gat was simulated and analyzed.As a result,the logic AND gate process signals with transmission speed of 10Gbit/s or below,and the external optical injection can effectively enhance the signal processing speed of SOA.It is useful to design all-optical logic gates based on SOA.
