Abstract
We propose a technique to improve the performance of high index contrast Multimode Interference (MMI) couplers. It is shown that imaging errors can be almost completely removed if the refractive index profile of the multimode region is properly designed. The proposed technique has been applied to design a 2×4 MMI 90° hybrid on SOI submicrometer strip waveguides (silicon-wires). Results show that the optimized device exhibits an almost ideal performance.
