A New Perspective on Plasmonics: Confinement and Propagation Length of Surface Plasmons for Different Materials and Geometries

Autor: Philippe Tassin, Babak Dastmalchi, Thomas Koschny, Costas M. Soukoulis

Publikováno v: Advanced Optical Materials. 4:177-184

Surface-plasmon polaritons are electromagnetic waves propagating on the surface of a metal. Thanks to subwavelength confinement, they can concentrate optical energy on the micrometer or even nanometer scale, enabling new applications in bio-sensing,

What is a good conductor for metamaterials or plasmonics

Autor: Thomas Koschny, Costas M. Soukoulis, Philippe Tassin, Nian-Hai Shen, Babak Dastmalchi

Publikováno v: Nanophotonics, Vol 4, Iss 1, Pp 69-74 (2015)

We review conducting materials like metals, conducting oxides and graphene for nanophotonic applications. We emphasize that metamaterials and plasmonic systems benefit from different conducting materials. Resonant metamaterials need conductors with s

Ellipsometry as a Nondestructive Depth Profiling Tool for Roll-to-Roll Manufactured Flexible Solar Cells

Autor: Morten Vesterager Madsen, Kurt Hingerl, Kion Norrman, Thomas Tromholt, Dechan Angmo, Frederik C. Krebs, Babak Dastmalchi, Matthieu Manceau, Kristian O. Sylvester-Hvid

Publikováno v: The Journal of Physical Chemistry C. 115:10817-10822

We show that it is possible to perform ellipsometry on large area roll-to-roll (R2R) coated solar cells on flexible substrates and further demonstrate that the slot-die coating technique employed yields the same bulk heterojunction (BHJ) film morphol

Publikováno v: Progress In Electromagnetics Research B. 26:39-52

Recently, we have introduced a numerical method for calculating local dispersion of arbitrary shaped optical waveguides, which is based on the Finite-Difierence Time-domain and fllter diagonalization technique. In this paper we present a study of

Publikováno v: ETRI Journal. 31:593-597

In this paper, we present a spatial perturbation method to control the optical patterns in semiconductor microresonators in the far-field configuration. We propose a fast all-optical switch which operates at a low light level. The switching beam cont

Publikováno v: 2014 16th International Conference on Transparent Optical Networks (ICTON).

Surface plasmon polaritons (SPP), supporting sub-wavelength confinement of light [1], enable a great potential for nanophotonic applications. SPP modes of flat interfaces, such as insulator-metal-insulator (IMI), and MIM geometries have been well inv

Strong group-velocity dispersion compensation with phase-engineered sheet metamaterials

Autor: Philippe Tassin, Costas M. Soukoulis, Babak Dastmalchi, Thomas Koschny

Publikováno v: Physical Review B. 89

Resonant metamaterials usually exhibit substantial dispersion, which is considered a shortcoming for many applications. Here we take advantage of the ability to tailor the dispersive response of a metamaterial introducing a new method of group-veloci
