Description
Summary:In this paper, we present a proposal for compact photonic wavelength filtering and 3-dB wavelength splitting device based on a nanoplasmonic metal-insulator-metal structure. The operating performance of the device has been accurately simulated using the temporal coupled-mode theory. We use a numerical simulation method of eigenmode expansion propagation in the overall design process. We show that the transmission efficiency of the drop filter can be significantly enhanced by applying specific optimization of nanotube waveguide. The proposed structure has potential applications in highly efficient, ultra-compact integrated circuits as well as in optical communication systems at the nanoscale size.
