Plasmonic low pass filter by nano rodes embedded in metal-insulator-metal waveguides

摘要

Since introducing plasmonic material, lots of efforts have been made to design and fabricate metallic optical structures by Ag and Au. These structures are used to overcome previous limitations such as guiding optical waves below the diffraction limit. A variety of plasmonic waveguides such as V-grooves, wedges, gaps, ring resonators, micro-cavities, etc as a part of these structures have been investigated in previous works.
