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 ...
The alternate-direction implicit finite difference beam propagation method (FD-BPM) is used to analyze the two-dimensional (2D) symmetrical multimode interference (MMI) couplers. The positions of the images at t...
