We report a waveguide crossing based on a multimode-interference （MMI） structure for metal-insulator-metal （MIM） waveguides. The MMI-based crossing comprises two orthogonal intersecting MMI waveguides that are connected to the single-mode input/output waveguide symmetrically. Single self-images are formed at the cross- ing center and output plane of the MMI waveguide, thereby mitigating the crosstalk and improving the through- put. The characteristics of the proposed MMI-based crossing are investigated with the finite element method of Comsol Multiphysics. The results show that the throughput reaches -1.8 dB and the crosstalk is less than -46 dB at the wavelength of 1550 nm.
