The performance of all-optical (AO) logic AND and OR gates, which are realized for the first time using reflective semiconductor optical amplifiers (RSOAs) as nonlinear elements, is theoretically investigated at 120 Gb / s. The switching modules that incorporate the RSOAs and exploit their potential for AO signal processing are the Mach–Zehnder interferometer and the delayed interferometer for the AND and OR operations, respectively. A performance comparison between an RSOA and a conventional semiconductor optical amplifier (SOA) is made by examining and assessing the quality factor against the operational critical parameters, including the effect of the amplified spontaneous emission. The obtained results confirm that these Boolean functions based on RSOAs can be executed at the target data rate with better performance than if conventional SOAs were used instead.

使用反射式半导体光放大器的 120 Gb/s 全光 AND 和 OR 逻辑门的理论研究

首次使用反射式半导体光放大器 (RSOA) 作为非线性元件实现的全光 (AO) 逻辑与门和或门的性能在 120 Gb / s 下进行了理论上的研究。包含 RSOA 并利用其 AO 信号处理潜力的开关模块分别是 Mach-Zehnder 干涉仪和用于 AND 和 OR 运算的延迟干涉仪。RSOA 和传统半导体光放大器 (SOA) 之间的性能比较是通过检查和评估质量因子与操作关键参数（包括放大的自发辐射的影响）来进行的。
