TLDR
The proposed coupler design has the advantages of improving the alignment tolerance of the plasmonic waveguide with respect to the dielectric waveguide and broadening the spectrum response of the splitter.
Abstract
In this paper, we present novel designs and analysis of ultra-compact couplers and 1 x 2 splitters based on plasmonic waveguides. Numerical simulation shows coupling efficiency up to 88% for the former one and 45% for each branch for the latter one. The proposed coupler design has the advantages of improving the alignment tolerance of the plasmonic waveguide with respect to the dielectric waveguide and broadening the spectrum response of the splitter.

Improved transmission model for metal-dielectric-metal plasmonic waveguides with stub structure

TL;DR: An improved analytical model describing transmittance of a metal-dielectric-metal (MDM) waveguide coupled to an arbitrary number of stubs is presented and it is shown that certain phase-matching conditions must be satisfied to provide opt al filtering characteristics for such waveguides.

Photonic signal processing on electronic scales: electro-optical field-effect nanoplasmonic modulator.

TL;DR: A highly efficient approach for the modulation of photonic signals at the nanoscale is developed, combining an ultrasubwavelength plasmonic guiding scheme with a robust electroabsorption effect in degenerate semiconductors.

Fano resonance in a MIM waveguide with double symmetric rectangular stubs and its sensing characteristics

TL;DR: In this paper, a metal-insulator-metal (MIM) type surface plasmon waveguide structure is designed, which is composed of a circular split-ring resonance cavity (CSRRC) and a double symmetric rectangular stub waveguide (DSRSW).

Surface plasmon subwavelength optics

TL;DR: By altering the structure of a metal's surface, the properties of surface plasmons—in particular their interaction with light—can be tailored, which could lead to miniaturized photonic circuits with length scales that are much smaller than those currently achieved.

A perfectly matched layer for the absorption of electromagnetic waves

TL;DR: Numerical experiments and numerical comparisons show that the PML technique works better than the others in all cases; using it allows to obtain a higher accuracy in some problems and a release of computational requirements in some others.

Surface Plasmons in Thin Films

TL;DR: In this article, the dispersion relations for surface plasma oscillations in normal metals are investigated for single-and multiple-film systems taking retardation effects into account, and two types of possible modes of oscillation are found.

Geometries and materials for subwavelength surface plasmon modes.

TL;DR: In this paper, the authors show that a metal-insulator-metal geometry is necessary and sufficient condition for subwavelength confinement of the optical mode, and the resulting trade-off between propagation and confinement for surface plasmons is discussed.

Bends and splitters in metal-dielectric-metal subwavelength plasmonic waveguides

TL;DR: In this article, the bends and splitters with no additional loss over a very wide frequency range were designed for metal-dielectric-metal waveguides with center layer thickness small compared to the wavelength.
