摘　　要：We discuss the optimal design of line-tapered multimode interference （MMI） devices using a genetic algorithm （GA）. A 1×4 MMI device is designed as a numerical example. Compared with the conventional design based on self-imaging theory, the present method demonstrates superior performance with low in- sertion loss and small non-uniformity.We discuss the optimal design of line-tapered multimode interference （MMI） devices using a genetic algorithm （GA）.
