This paper presents a new design method for all-optical NAND and AND logic gates based on 3x3 geneial interference multimode interference (GI MMD coupler. The whole device is realizedon the silicon on insulator (SOI) platform. The transfer matrix method (TMM) and three dimensional beam propagation method (3D-BPM) are used to optimally design these devices.
