DNA origami assembled nanoantennas for manipulating single-molecule spectral emission
Maria Sanz-Paz, Fangjia Zhu, Nicolas Bruder +3
Optical nanoantennas can affect the decay rates of nearby emitters by modifying the local density of photonic states around them. In the weak-coupling limit, and according to the F…
Unidirectional ultracompact DNA-templated optical antennas
Fangjia Zhu, Maria Sanz-Paz, Antonio Fernandez-Dominguez +5
Optical nanoantennas are structures designed to manipulate light-matter interactions at the nanoscale by interfacing propagating light with localized optical fields. In recent year…
Optical ultracompact directional antenna based on a dimer nanorod structure
Fangjia Zhu, Maria Sanz-Paz, Antonio Fernandez-Dominguez +2
Controlling directionality of optical emitters is of utmost importance for their application in communication and biosensing devices. Metallic nanoantennas have been proven to affe…
Optimization of second-harmonic generation from touching plasmonic wires
Shimon Elkabetz, K. Nireekshan Reddy, Parry Y. Chen +2
We employ transformation optics to optimize the generic nonlinear wave interaction of second-harmonic generation from a pair of touching metallic wires. We demonstrate a 10 orders…
Magnetic-field controlled anomalous refraction in doped semiconductors
E. Moncada-Villa, A. I. Fernández-Domínguez, J. C. Cuevas
We predict here that a slab made of a doped semiconductor can exhibit anomalous refraction under the application of a static magnetic field. This anomalous refraction takes place i…
Harvesting Light with Transformation Optics
Yu Luo, Rongkuo Zhao, Antonio I. Fernandez-Dominguez +2
Transformation optics (TO) is a new tool for controlling electromagnetic fields. In the context of metamaterial technology, it provides a direct link between a desired electromagne…
Geometrically induced modification of surface plasmons in the optical and telecom regimes
M. L. Nesterov, D. Martin-Cano, A. I. Fernandez-Dominguez +3
We demonstrate that the introduction of a subwavelength periodic modulation into a metallic structure strongly modifies the guiding characteristics of the surface plasmon modes sup…
Optical properties of carbon nanofiber photonic crystals
R. Rehammar, R. Magnusson, A. I. Fernandez-Dominguez +4
Carbon nanofibers (CNF) are used as components of planar photonic crystals. Square and rectangular lattices and random patterns of vertically aligned CNF were fabricated and their…
