Paper Abstract

Using the cross-gain modulation (XGM) characteristics of semiconductor optical amplifiers (SOAs), multi-functional all-optical logic gates including XOR, AND, and OR gates are successfully demonstrated at 10 Gbps by using VPI component makerTM simulation tool. Multi-quantum well (MQW) SOA is used for the simulation of all-optical logic system. Our suggested system is composed of four MQW SOAs, SOA-1 and SOA-2 for XOR logic operation and SOA- 3 and SOA-4 for AND logic operation. By the addition of two output signals XOR and AND, all-optical OR logic can be obtained.
