摘　　要：对基于半导体光放大器和Sagnac干涉仪(Semiconductor Optical Amplifier Sagnac Interferometer,SOA-SI)的全光逻辑门进行理论研究。将泵浦信号作为控制信号,分析泵浦功率对SOA的载波数和增益的影响,并利用SOA-SI方案来实现异或门、或非门。仿真实验中,T端口和R端口的消光比分别为14.47 dB和5.12 dB.Q因子分别为8.79 dB和7.92 dB,比特误码率分别低至1.82×10^(14)和2.80×10^(10),眼图良好的张开度表明,在T和R端口的输出信号均具有较高的逻辑正确性和品质。This paper conducts theoretical research on all-optical logic gate configuration based on semiconductor optical amplifier and Sagnac interferometer(SOA-SI). By using the pump signal as a control signal, it analyzes the influence of pump power on the carrier number and gain of SOA, and uses the SOA-SI scheme to implement XOR gate or NOR gate together. In the simulation experiment, the extinction ratio(ER) are 14.47 dB and 5.12 dB, Q factor are 8.79 dB and 7.92 dB, bit error rate(BER) is as low as 1.82×10^(-14) and 2.80×10^(-10). The good opening of eye-diagram clearly show that these output signals at T-and R-port have both high logic correctness and high quality.
