“…The MIM waveguides studied previously have symmetric structure, meaning that the metals at the top and bottom of the dielectric layer are the same [14,15]. Also, asymmetric MIMs have not been investigated, and to the best of our knowledge, a few researchers have investigated the nonlinear optical phenomena in these asymmetric waveguides.…”

“…Plasmonic waveguides, based on insulator-metal-insulator waveguides, have been studied extensively as well [9,10]. However, metal-insulator-metal (MIM) waveguides have higher confinement factors and closer spacing to adjacent waveguides [11,12] and have been proposed for a lot of applications such as optical resonators, waveguide bends and splitters based on MIM sub-wavelength plasmonic waveguides [13][14][15].…”

In this study, it was shown that field enhancement in the nonlinear metal-insulator-metal (MIM) plasmonic waveguides can result in a large enhancement of the second harmonic generation (SHG) magnitude as compared with values reported in the literature. The proposed structure has two metals at the top and two metals at the bottom of the crystal. In this structure, a voltage is applied on metals to produce a SHG electrically. Hence, the metals that define the cavity also serve as electrodes capable of generating high direct current electric fields across the nonlinear material. The frequency of a fundamental wave at 458 nm was doubled and modulated in intensity by applying a moderate external voltage to the electrodes, yielding a voltage-dependent nonlinear generation with a higher coupling efficiency. All the simulations here have been calculated by using the finite-element-based commercial COMSOL software.

“…For objects much smaller than the incident wavelength, the induced polarization is resonant at modes whose number and strength vary with the scatterer's shape and dimensions [71,91]. At these resonant frequencies the local fields near the scattering center are very high, and both the absorption cross section and the scattering cross section of the object will be at maximum.…”

“…As the understanding of the transmission mechanism improved, the high transmission observed in this structure were linked not only to the surface plasmon waves but also to surface waves of the corrugated surface for the case of perfect electrical conductors (PECs) [12]. Planar MIM structures, on their part, have been investigated theoretically for decades now [13] and have gain interest recently with new experimental demonstrations [3,14,15] as well as extended analysis for integration into nanoscale devices [16].…”

A semi-analytical formalism for the optical properties of a metal-insulator-metal periodic nanostructure using coupled-mode theory is presented. This structure consists in a dielectric layer in between two metallic layers with periodic one-dimensional nanoslit corrugation. The model is developed using multiple-scattering formalism, which defines transmission and reflection coefficients for each of the interface as a semi-infinite medium. Total transmission is then calculated using a summation of the multiple paths of light inside the structure. This method allows finding an exact solution for the transmission problem in every dimension regime, as long as a sufficient number of diffraction orders and guided modes are considered for the structure. The resonant modes of the structure are found to be related to the metallic slab only and to a combination of both the metallic slab and dielectric layer. This model also allows describing the resonant behavior of the system in the limit of a small dielectric layer, for which discontinuities in the dispersion curves are found. These discontinuities result from the out-ofphase interference of the different diffraction orders of the system, which account for field interaction for both inner interfaces of the structure.
