Plasmonic modes in W-shaped metal-coated silicon grooves.
Measurements of a W-shaped metal-coated surface Plasmon polariton waveguides are presented, showing complex confined modes both in the coupled pair of air filled metal V-grooves, as well as within the central metal-coated triangular silicon wedge. Mode calculations support the experimentally measured plasmonic modes. Such W-shaped plasmonic waveguides when integrated with Metal-Oxide-Silicon structures may be utilized for active plasmonic nano-optical devices.
