“…Over the past ten years, tremendous developments have occurred in the field of surface plasmon polaritons (SPPs)-propagating electromagnetic waves at a dielectric-metal interface [1][2][3][4][5][6][7]. The strong confinement and local field enhancement associated with SPPs enables them to resolve spatial detail beyond the diffraction limit.…”

Abstract:Using a finite-element, full-wave modeling approach, we present a flexible method of analyzing and simulating dielectric and plasmonic waveguide structures as well as their mode coupling. This method is applied to an integrated plasmonic circuit where a straight dielectric waveguide couples through a straight hybrid long-range plasmon waveguide to a uniformly bent hybrid one. The hybrid waveguide comprises a thin metal core embedded in a two-dimensional dielectric waveguide. The performance of such plasmonic circuits in terms of insertion losses is discussed.

“…Such type of the waveguides is included as a key part in many structures (e.g. Metal insulator metal waveguide with bends [24], as a part of the split-ring resonators [25], or as a subwavelength hole in a thick screen [26], or as an approximation model for V-groove waveguide [27]), waveguide arrays, etc. (see [28] and references there).…”

“…(see [28] and references there). The developed nanooptics increases an interest to the theory of a light in the planar waveguides characterized by various geometry and material properties [24,26,[29][30][31][32][33][34][35][36]. Now the researchers need to use the numerical methods providing only numerical data of the calculations restricted by the concrete physical and geometrical parameters of the planar waveguides.…”

“…The existing theoretical approaches permit only the approximate solutions of the transcendental equation in three limiting cases: i) near cuttoff, ii) at short-wave limit Lω/c ≫ 1, and iii) in the strongly asymmetrical case (see, for example [22]). While the nanowaveguide structures characterized by the intermediate sizes (Lω/c ≤ 1) are studied only by the numerical methods [22,43] (see also recent works [24][25][26][27][29][30][31][32][33][34][35][36]).…”

A transversely localized light in a waveguide: the analytical solution and its potential application

Investigation of light in the waveguide structures is a topical modern problem that has long historical roots. A parallel-plate waveguide is a base model in these studies and it is intensively used in numerous investigations of nanooptics, integrated circuits and nanoplasmonics. In this letter we first have found the analytical solution for the light modes in this waveguide. The solution provides a clear physical picture for description of a light within the broadband spectral range in the waveguide with various physical parameters. Potential of the analytical solutions for studies of light fields in the waveguides of nanooptics and nanoplasmonics has been also discussed.

“…6, we show jE x ω 1 j in the middle of the gap region for six λ 1 values in the range of analysis; the interface air/GaAs is at y 0 50 nm (the other components have qualitatively similar distributions). The gap region acts as a metal-insulatormetal (MIM) waveguide [29] with boundary conditions imposed by the geometry of the structure. The multi-spot field distribution we observe in the gap is typical of a Fabry−Perot cavity, and it depends on cavity dimensions and wavelength [30].…”

A plasmonic metasurface for the enhancement of nonlinear optical effects is proposed. The metasurface can simultaneously enhance perpendicularly polarized electric fields in the same volume. We illustrate application of the metasurface to the production of Terahertz radiation via the parametric process of difference frequency generation in 4¯3m non-centro symmetric materials, e.g., GaAs, which has a large second-order nonlinear susceptibility. An enhancement over bulk of almost two orders of magnitude near the surface supports the use of the proposed structure for thin-film, surface-based, or chip-based nonlinear optical applications for several crystal classes.
