In recent years, plasmonic nano-antennas have been used in a wide range of applications in sensing, particle detection, imaging and Surface Enhanced Raman Scattering (SERS) detection. Also, arrays of nano-antennas have been recently developed to produce more directional radiation beams or to operate over a wide range of wavelengths. In this article, it is shown that small arrays of nano-antennas can be created by recycling the power that flows through their antenna gaps.

Titanium nitride (TiN) is a novel refractory plasmonic material which can sustain high temperatures and exhibits large optical nonlinearities, potentially opening the door for high-power nonlinear pla...
Nano-antennas are the optical equivalent of antennas that are used to transmit and receive information at radio frequencies. These antennas have been used in different applications in photonics such a...
We introduce an efficient, single-mode, linearly polarized continuous wave (CW) Raman fiber laser (RFL), operating at 1178 nm, with 65 W maximum output power and a narrow linewidth of 0.1 nm. Single-p...
In this Letter, the focal spot areas of an azimuthally polarized beam modulated with a vortex-0-2π-phase plate or a π-phase-step plate are numerically found to be smaller than a radially polarized b...
Nonlinear phenomena are central to modern photonics but, being inherently weak, typically require gradually accumulation over several millimetres. For example, second harmonic generation (SHG) is typi...
This study is an open-label, prospective pharmacokinetic study investigating two antiretroviral agents in parallel and employing an adaptive design with two stages, whereby the results obt...

This study valuates the safety and efficacy of treatment with 3% Diclofenac Nano-Emulsion Cream versus Placebo in subjects with osteoarthritis of the knee.
Microscopy using polarized light in which phenomena due to the preferential orientation of optical properties with respect to the vibration plane of the polarized light are made visible and correlated parameters are made measurable.
Large vessels propelled by power or sail used for transportation on rivers, seas, oceans, or other navigable waters. Boats are smaller vessels propelled by oars, paddles, sail, or power; they may or may not have a deck.
The rotation of linearly polarized light as it passes through various media.
The property of nonisotropic media, such as crystals, whereby a single incident beam of light traverses the medium as two beams, each plane-polarized, the planes being at right angles to each other. (Cline et al., Dictionary of Visual Science, 4th ed)
A change from planar to elliptic polarization when an initially plane-polarized light wave traverses an optically active medium. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
