Journal ArticleDOI
A hybrid plasmonic waveguide for subwavelength confinement and long-range propagation
TL;DR: In this article, a hybrid optical waveguide is proposed to confine surface plasmon polaritons over large distances using a dielectric nanowire separated from a metal surface by a nanoscale gap.
Journal ArticleDOI
Confinement and propagation characteristics of subwavelength plasmonic modes
TL;DR: In this article, the authors studied subwavelength confinement of the surface plasmon polariton modes of various waveguides and examined their relative merits using a graphical parametric representation of their confinement and propagation characteristics.
Journal ArticleDOI
Channel plasmon-polariton in a triangular groove on a metal surface.
David Pile,Dmitri K. Gramotnev +1 more
TL;DR: It is demonstrated that the localization of the predicted plasmons in acute grooves may be substantially stronger than what is allowed by the diffraction limit.
Journal ArticleDOI
Two-dimensionally localized modes of a nanoscale gap plasmon waveguide
David Pile,Takeshi Ogawa,Dmitri K. Gramotnev,Yosuke Matsuzaki,Kristy C. Vernon,Kenzo Yamaguchi,Toshihiro Okamoto,Masanobu Haraguchi,Masuo Fukui +8 more
TL;DR: In this paper, the authors report numerical analysis and experimental observation of two dimensionally localized plasmonic modes guided by a nanogap in a thin metal film using the finite-difference time-domain algorithm.
Journal ArticleDOI
Theoretical and experimental investigation of strongly localized plasmons on triangular metal wedges for subwavelength waveguiding
David Pile,Takeshi Ogawa,Dmitri K. Gramotnev,Takeshi Okamoto,Masanobu Haraguchi,Masuo Fukui,Shigeki Matsuo +6 more
TL;DR: In this article, the authors report numerical analysis and experimental observation of strongly localized plasmons guided by a triangular metal wedge and analyze their dispersion and dissipation using the finite-difference time-domain algorithm.
