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 proposed demultiplexer design is integrated on a MIMwaveguide such that power is evanescently coupled into an array of appropriately designed cavity-groove combination. The demultiplexer design permits control of phase of the dropped wavelength to achieve a desired wavefront. We demonstrate this through generation of circular and plane wavefront. By controlling the evanescently coupled power into the cavitygroove combinations, it is possible to dramatically improve the efficiency of the proposed demultiplexer. Results are simulated using FEM technique.
