Paper Abstract

In this paper, a surface plasmon waveguide structure consisting of annular gap and metal-insulator-metal waveguides is proposed, and its spectral characteristics are analyzed and studied. The results show that this waveguide structure has good performance in narrowband filtering in sub-wavelength band, and the central wavelength of the transmission peak is linearly related to the angle of the annular with notch. The results are of great significance for the application of filtering structures in highly integrated photonic circuits.
