“…In Appendix B we calculate the J(α; Q) function [Eq. (16)] for the Gaussian profile. From here on, we will consider the transverselylocalized plasmons case only, that is, for a given q y , the maximum frequency that we consider is given by Eq.…”

We derive an integral equation describing surface-plasmon polaritons in graphene deposited on a substrate with a planar surface and a dielectric protrusion in the opposite surface of the dielectric slab. We show that the problem is mathematically equivalent to the solution of a Fredholm equation, which we solve exactly. In addition, we show that the dispersion relation of the channel surface plasmons is determined by the geometric parameters of the protrusion alone. We also show that such system supports both even and odd modes. We give the electrostatic potential and the intensity plot of the electrostatic field, which clearly show the transverse localized nature of the surface plasmons in a continuous and flat graphene sheet. arXiv:1801.03801v3 [cond-mat.mes-hall]

“…In order to explore fundamental limitations, one has to consider the limit of vanishing radii of curvature. While subnanometer radii appear unrealistic for nanowires, fabrication of grooves cut in metal and metal wedges, e.g., by nanoimprint lithography [29], can in fact result in nmsharp edges with corresponding nm-sized wedge modes [4]. We expect that nonlocal effects then come into play.…”

We present a novel wave equation for linearized plasmonic response, obtained by combining the coupled real-space differential equations for the electric field and current density. Nonlocal dynamics are fully accounted for, and the formulation is very well suited for numerical implementation, allowing us to study waveguides with subnanometer cross-sections exhibiting extreme light confinement. We show that groove and wedge waveguides have a fundamental lower limit in their mode confinement, only captured by the nonlocal theory. The limitation translates into an upper limit for the corresponding Purcell factors, and thus has important implications for quantum plasmonics.

“…Among the previously studied surface plasmon polariton (SPP) structures for subwavelength light confinement and guiding, triangular metallic grooves supporting the propagation of channel plasmon polaritons (CPPs) have been intensively investigated for their capability of simultaneously providing tight light confinement and long propagation distance [3][4][5][6][7]. Another merit is their ease of fabrication, which has enabled a number of experimental demonstrations [8][9][10][11][12].…”

Plasmonic waveguides consisting of metallic grooves filled with low-and high-index dielectrics are proposed and the optical properties of guided plasmonic modes are investigated at a wavelength of 1550 nm. Numerical simulations reveal that the quasi-TE-like fundamental hybrid plasmonic mode exhibits strong localization near the low-index dielectric gap, along with pronounced local field enhancement and relatively small mode area. Moderate propagation loss can be achieved as well, corresponding to a propagation distance of around tens to hundreds of microns. The proposed hybrid plasmonic structure is compatible with the fabrication techniques of traditional channel plasmon polariton waveguides, and these structures could be employed as interesting building blocks for highly integrated photonic circuits.
