一种基于SOA-MZI的新型全光逻辑非门分析

In recent years, the ever growing Internet applications and various multimedia services have been exerting heavy burden on current telecommunication networks and the operation speed of telecommunication systems is approaching the limit of electronics. All-optical switching and all-optical bit-level processing will likely play a crucial role to avoid cumbersome and power-consuming electro-optic conversion. Ultrafast all-optical logic gates are expected to make up the central element in a wide variety of signal processing functionalities. In this paper, a novel all-optical NOT gate based on the XPM effect in SOA-MZI are proposed. Theoretical analysis and numerical simulations are performed to validate and optimized the logical gates. Consequently, several rules and limits on the parameter design are drawn.
