Comparison of Waveguiding Properties of Plasmonic Voids and Plasmonic Waveguides
The Journal of Physical Chemistry C, 2010Here we compare different nanoscale waveguiding geometries involving plasmonic materials for subdiffractive propagation at optical frequencies. Deriving closed-form analytical formulas to analyze the different structures, we show how the presence of a plasmonic background may produce robust, highly confined guided wave propagation as compared with the ...

Photon plasmon coupling in nanocomposite plasmonic waveguides
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014The propagation of Surface Plasmon Polaritons (SPP) presents high interest nowadays because its hybrid nature in between electromagnetic and surface charge waves that allows exotic properties like subwavelength confinement, strong near electric field or high sensitivity to the environment.

Gap plasmon excitation into plasmonic waveguide using Si waveguide
2015 20th Microoptics Conference (MOC), 2015We have fabricated a junction of a Si waveguide to plasmonic waveguide supporting the second plasmon mode as a first step to realize high density integrated optical circuit. We successfully excited the second plasmonic mode by using Si waveguide and evaluated that the coupling efficiency is about 7.5%.

This chapter investigates the properties of the modes supported by three-dimensional subwavelength plasmonic slot waveguides. It shows 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.

Gap plasmon excitation in plasmonic waveguide using Si waveguide
Japanese Journal of Applied Physics, 2016Abstract Plasmonic waveguides have attracted considerable attention for application in highly integrated optical circuits since they can confine light to areas smaller than the diffraction limit. In this context, in order to realize a highly integrated optical circuit, we fabricate and evaluate the optical characteristics of a poly ...

Waveguiding with Surface Plasmon Polaritons
2014Surface plasmon polaritons (SPPs) are electromagnetic modes propagating along metal-dielectric interfaces. Various SPP modes can be supported by flat and curved, single and multiple surfaces, exhibiting remarkable properties, including the possibility of concentrating electromagnetic fields beyond the diffraction limit, i.e., on the nanoscale, while ...

SUBWAVELENGTH-SCALE PLASMON WAVEGUIDES
2007By the mid-17th century, numerous scientists—notably including Hooke and Gallileo—had developed transparent ground lenses and applied them in the construction of compound optical microscopes. This development revolutionized the contemporary understanding of the natural world by, for example, enabling the imaging of blood cells and microbes.

Plasmonic waveguiding and focusing
IEEE Photonics Society Summer Topicals 2010, 2010We explore two main representative fields of plasmonics: plasmonic focusing and waveguiding. We overview and discuss several methods of focusing and waveguiding electromagnetic fields in subwavelength regime using plasmonics.

Slow Surface Plasmons in Plasmonic Grating Waveguide
IEEE Photonics Technology Letters, 2013A metal/air/metal (MAM) plasmonic grating waveguide (PGW) consisting of two parallel silver slabs with periodic corrugations on their inner boundaries is developed to slow down the group velocity of surface plasmon polaritons (SPPs) excited at near-infrared frequencies.
