Abstract

Cross-shaped resonator topologies for realization of metal–insulator–metal (MIM) plasmonic filters are introduced and comprehensively studied. The structures are numerically simulated using finite difference time domain method. It is shown that single-mode MIM filters can be obtained using the proposed topologies for the wavelength range of 400 nm to 2 μm. Analytical formulas for designing the filters have also been proposed. As an important application, the cross-shaped resonators can be used for design of low-cross-talk waveguide intersections. The simplicity of the design, the ability to use analytical formulas, and obtaining a single-mode resonance are the benefits of the proposed cross-shaped topologies.
