Design and performance of all optical ternary NOT & XOR gate using the Dual semiconductor optical amplifier (SOA)-based technology is investigated. The basic principal behind the operation of these logic gates is nonlinear cross-polarization modulation (XPolM) effect in SOA. Optical NOT gate is universal logic gate, and optical XOR gates are very useful in designing higher order optical devices like flip-flops, parity checker and generator circuits, etc. The Q-value of the design is greater than 50 dB maintaining high operational speed (~ 100Gbit/s) ensures negligible bit error rate. Numerical simulation using MATLAB ensures CR values more than 55 dB and ER values more than 50 dB. These high values ensure practical feasibility of the proposed devices. The large relative eye opening(> 94%) ensures clear transmissions of the information.

研究了基于双半导体光放大器（SOA）技术的所有三元非与非门的设计和性能。这些逻辑门的操作背后的基本原理是SOA中的非线性交叉极化调制（XPolM）效应。光学“非”门是通用逻辑门，光学“异或”门在设计高阶光学器件（如触发器，奇偶校验器和发生器电路等）中非常有用。设计的Q值大于50 dB，可保持较高的工作速度（〜100Gbit / s）确保可以忽略的误码率。使用MATLAB进行数值模拟可确保CR值大于55 dB，ER值大于50 dB。这些高值确保了所提出设备的实际可行性。相对大的眼图张开度（> 94％）确保了信息的清晰传输。
