Abstract

In this paper, 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 sel-image theory, the GA optimization demonstrates good performances such as a low insertion and small non-uniformity.
