Optimization of line-tapered MMI devices using a genetic algorithm被引量:2
《Chinese Optics Letters》2009年第11期1045-1047,共3页肖永生 周建江 李淑静 黄丽贞 郜定山 吴华明 
supported in part by the National "973" Program of China (No.2006CB708310);the National Natural Science Foundation of China (No.60706013);Wuhan National Laboratory for Optoelectronics
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 ...
