The size of electronic circuits-can be below 1OOnm, but the size of an optical component is on the order of micron because of optical diffraction. Metal/dielectric sub-wavelength waveguide is considered as one of the leading technologies to integrating optical and electronic devices in the future.We study the dispersive model of MIM, and design a 1×3 MMI power splitter based on multimode interference principle in MIM structure. Then the COMSOL is used to simulate the magnetic field distribution.
