Journal ArticleDOI
Magnetic and electric coherence in forward- and back-scattered electromagnetic waves by a single dielectric subwavelength sphere
Jean-Michel Geffrin,Braulio García-Cámara,Braulio García-Cámara,R. Gómez-Medina,Pablo Albella,Luis S. Froufe-Pérez,Christelle Eyraud,Amelie Litman,Rodolphe Vaillon,Francisco González,Manuel Nieto-Vesperinas,Juan José Sáenz,Juan José Sáenz,Fernando Moreno +13 more
TL;DR: Experimental evidence is presented that a single low-loss dielectric subwavelength sphere of moderate refractive index radiates fields identical to those from equal amplitude crossed electric and magnetic dipoles, and indistinguishable from those of ideal magnetodielectric spheres, and these Kerker scattering conditions only depend on a/λ.
Journal ArticleDOI
Non-plasmonic nanoantennas for surface enhanced spectroscopies with ultra-low heat conversion.
Martín Caldarola,Pablo Albella,Emiliano Cortés,Mohsen Rahmani,Tyler Roschuk,Gustavo Grinblat,Rupert F. Oulton,Andrea V. Bragas,Stefan A. Maier +8 more
TL;DR: It is shown that dimer-like silicon-based single nanoantennas produce both high surface enhanced fluorescence and surface enhanced Raman scattering, while at the same time generating a negligible temperature increase in their hot spots and surrounding environments.
Journal ArticleDOI
Low-loss electric and magnetic field-enhanced spectroscopy with subwavelength silicon dimers
Pablo Albella,Pablo Albella,M. Ameen Poyli,Mikolaj K. Schmidt,Stefan A. Maier,Fernando Moreno,Juan José Sáenz,Javier Aizpurua +7 more
TL;DR: In this article, the electromagnetic behavior of the basic unit constituted by a dimer of dielectric nanoparticles made of moderately low-loss high refractive index material is explored and studied through an analytical dipole-dipole model.
Journal ArticleDOI
All-optical control of a single plasmonic nanoantenna-ITO hybrid.
TL;DR: The combination of tunable antenna-ITO hybrids with nanoscale plasmonic energy transfer mechanisms, as demonstrated here, opens a path for new ultrafast devices to produce nanoplasmonics switching and control.
Journal ArticleDOI
Resolving the electromagnetic mechanism of surface-enhanced light scattering at single hot spots
Pablo Alonso-González,Pablo Albella,Martin Schnell,Jianing Chen,Florian Huth,Aitzol García-Etxarri,Aitzol García-Etxarri,Aitzol García-Etxarri,Fèlix Casanova,Federico Golmar,Libe Arzubiaga,Luis E. Hueso,Javier Aizpurua,Rainer Hillenbrand +13 more
TL;DR: Experimental evidence is provided that the intensity elastically scattered off the object scales with the fourth power of the local field enhancement provided by the antenna, and that the underlying electromagnetic mechanism is identical to the one commonly accepted in surface-enhanced Raman scattering.
