Effective skyrmion number for mixed polarization states of light
Rosario MartÃnez-Herrero, Ãngel S. Sanz
Polarization skyrmions are usually characterized through a unit Stokes vector field, which defines a map from the transverse plane to the Poincaré (Bloch) sphere and allows one to…
Azimuthal super-pupil beam engineering for improved fluorescence depletion microscopy
Costanza Agazzi, Nick Toledo-GarcÃa, Estela MartÃn-Badosa +5
Fluorescence depletion microscopy techniques such as STED and RESOLFT require optical fields with a well-defined and spatially confined central intensity minimum to achieve sub-dif…
Engineering of self-bending surface plasmon polaritons through Hermite-Gaussian mode expansion
J. Hernández-Rueda, A. S. Sanz, R. MartÃnez-Herrero
Surface plasmon polaritons have received much attention over the last decades in photonics or nanotechnology due to their inherent high sensitivity to metal surface variations (e.g…
Tailored Hotspots from Airy-Based Surface Plasmon Polaritons
Rosario MartÃnez-Herrero, Ãngel S. Sanz, Javier Hernandez-Rueda
Surface plasmons have attracted growing interest from the photonics community due to their inherent ability to controllably confine light below the diffraction limit and their dire…
Exploring the dynamics of finite-energy Airy beams: A trajectory analysis perspective
A. S. Sanz, R. MartÃnez-Herrero
In practice, Airy beams can only be reproduced in an approximate manner, with a limited spatial extension and hence a finite energy content. To this end, different procedures have…
