Abstract

The authors present a nano-plasmonic disk resonator with a gap structure using the multi-mode interference effect coupling. The coupling intensity of the multi-mode interference effect coupling is 1.5 times greater than that of the conventional side coupling. The multi-mode interference effect is adopted as the coupling between the input bus waveguide and the nano-plasmonic disk resonator. The thickness of the dielectric layer, the width of the bus waveguide, and the length of the coupling portion are designed by theoretical calculations.
