چکیده
In this paper, the propagation properties of Surface Plasmon Polariton mode in Metal-Insulator-Metal waveguide are presented. An additional thin metallic film is inserted inside the insulator for higher confinement. Silver (Ag) has been taken as the metal and air, gallium lanthanum sulphide (GLS) and aluminum gallium arsenide (AlGaAS) as the insulators for the construction of the waveguide. Finally the propagation loss of SPP over the length of waveguide constructed with different materials has been analyzed and presented. General Terms Plasmonic Waveguide, Finite-Difference Time-Domain, Surface Plasmon Polariton (SPP), Material dispersion, SPP mode.

Metal-coated hollow nanowires for low-loss transportation of plasmonic modes with nanoscale mode confinement
Two types of plasmonic waveguiding structures based on hollow dielectric nanowires are proposed and their modal properties are investigated numerically at a wavelength of 1550 nm. The first type of waveguide consists of a high-index hollow nanowire covered directly by a thin metallic film. Depending on the size of the hollow nanowire, such a waveguide could support a plasmonic mode with lower p...

We demonstrate a novel route to achieving highly efficient and strongly confined spoof surface plasmon polaritons (SPPs) waveguides at subwavelength scale enabled by planar staggered plasmonic waveguides (PSPWs). The structure of these new waveguides consists of an ultrathin metallic strip with periodic subwavelength staggered double groove arrays supported by a flexible dielectric substrate, l...
متن کاملLow loss coupler to interface silicon waveguide and hybrid plasmonic waveguide
A metallic coupler is proposed to interface a silicon on insulator (SOI) waveguide with a narrow hybrid plasmonic waveguide (200× 200 nm). The device operation is investigated and optimized to attain the best tradeoff between the mode confinement and the propagation loss. Calculations reveal that a high confinement and low loss of the energy is achieved from a silicon slab waveguide into the di...
متن کاملProperties of three-dimensional plasmonic slot waveguides
We investigate the properties of the modes supported by three-dimensional subwavelength plasmonic slot waveguides. We show that the fundamental mode supported by a symmetric plasmonic slot waveguide, composed of a subwavelength slot in a thin metallic film embedded in an infinite homogeneous dielectric, is always a bound mode. Its modal fields are highly confined over a wavelength range extendi...
متن کاملAdjustable Plasmonic Bandgap in One-Dimensional Nanograting Based on Localized and Propagating Surface Plasmons
Compared to the long history of plasmonic gratings, there are only a few studies regarding the bandgap in the propagation of plasmonic surface waves. Considering the previous studies on interpretation of plasmonic bandgap formation, we discuss this phenomenon using the effect of both surface plasmon polariton (SPP) and localized surface plasmon (LSP) for our fabricated one-dimensional metallic-...
