An efficient wavelength demultiplexer with its input as a metal-insulator-metal (MIM) waveguide mode and output an out of plane free-space mode is proposed. The proposeddemultiplexer design is integrated on a MIMwaveguide such that power is evanescently coupled into an array of appropriatelydesigned cavity-groove combination. The demultiplexerdesign permits control of phase of the dropped wavelengthto achieve a desired wavefront. We demonstrate thisthrough generation of circular and plane wavefront. By controllingthe evanescently coupled power into the cavitygroovecombinations, it is possible to dramatically improvethe efficiency of the proposed demultiplexer. esults are simulatedusing FEM technique
