Abstract

A compact 4×4 Multimode Interference（MMI） combiner with the size of 3 890 μm×100 μm is designed by making use of the advantage of the InP-based air-restricted waveguide in small bending radius.A tapered waveguide is inserted between the input/output waveguides and the MMI zones

effectively improving the performance of the combiner.The device is simulated by the three-dimensional wide-angle beam propagation method

obtaining the optimized parameter values and thus optimizing its structure.
