Journal ArticleDOI
Efficient unidirectional nanoslit couplers for surface plasmons
F. López-Tejeira,Sergio G. Rodrigo,Luis Martín-Moreno,Francisco J. Garcia-Vidal,Eloïse Devaux,Thomas W. Ebbesen,Joachim R. Krenn,Ilya P. Radko,Sergey I. Bozhevolnyi,María Ujué González,Jean-Claude Weeber,Alain Dereux +11 more
TL;DR: In this paper, a back-side slit-illumination method that incorporates a periodic array of grooves carved into the front side of a thick metal film was proposed to enhance the propagation of SPPs away from the array, enabling them to be unidirectionally launched from, and focused to, a localized point.
Journal ArticleDOI
Guiding and focusing of electromagnetic fields with wedge plasmon polaritons.
Esteban Moreno,Sergio G. Rodrigo,Sergey I. Bozhevolnyi,Luis Martín-Moreno,Francisco J. Garcia-Vidal +4 more
TL;DR: These modes are found to exhibit superior confinement while showing similar propagation loss as compared to other subwavelength guiding configurations, and it is shown that mode focusing can be realized by gradual modification of the wedge geometry along the mode propagation direction.
Journal ArticleDOI
Channel plasmon-polaritons: modal shape, dispersion, and losses
Esteban Moreno,Francisco J. Garcia-Vidal,Sergio G. Rodrigo,Luis Martín-Moreno,Sergey I. Bozhevolnyi +4 more
TL;DR: It is shown that, with an increase of the wavelength, the fundamental CPP mode shifts progressively toward the groove opening, ceasing to be guided at the groove bottom and becoming hybridized with wedge plasmon-polaritons running along the groove edges.
Journal ArticleDOI
Triangular metal wedges for subwavelength plasmon-polariton guiding at telecom wavelengths
Alexandra Boltasseva,Valentyn S. Volkov,Rasmus Nielsen,Esteban Moreno,Sergio G. Rodrigo,Sergey I. Bozhevolnyi +5 more
TL;DR: A high-quality fabrication procedure for making gold wedge waveguides, which is also mass-production compatible offering large-scale parallel fabrication of plasmonic components, is developed and experimental observations are consistent with numerical simulations performed with the multiple multipole and finite difference time domain methods.
Journal ArticleDOI
Influence of material properties on extraordinary optical transmission through hole arrays
TL;DR: In this paper, the optical response of circular hole arrays drilled in several metal films (Ag, Au, Cu, Al, Ni, Cr, and W) was studied. But the authors only considered the case of Ni and Cr.
