Abstract

We design and optimize highly compact plasmonic switches with high modulation depth and moderate insertion loss, consisting of a metal-dielectric-metal waveguide coupled to a subwavelength cavity resonator. We consider a multisection cavity resonator which comprises multiple sections of varying widths. We find that the optimal structure is a perturbation of the maximum size cavity obtained by reducing the width of the middle section in order to tune the resonant wavelength of the cavity. In addition, the on-resonance modulation depth of the optimized multisection cavity switch is greatly enhanced with respect to a conventional Fabry–Perot cavity switch. We use a single-mode scattering matrix theory to account for the behavior of these systems.
