Correlations between helicity and optical losses within general electromagnetic scattering theory
Jon Lasa-Alonso, Jorge Olmos-Trigo, Aitzol García-Etxarri +1
Helicity preserving nanostructures and metasurfaces have been recently proposed as suitable candidates to enhance spectroscopic features of chiral matter. With this in mind, we hig…
Bandwidth control of the biphoton wavefunction exploiting spatio-temporal correlations
J. J. Miguel Varga, Jon Lasa-Alonso, Martín Molezuelas-Ferreras +2
In this work we study the spatio-temporal correlations of photons produced by spontaneous parametric down conversion. In particular, we study how the waists of the detection and pu…
Multiple Kerker anapoles in dielectric microspheres
Cristina Sanz-Fernández, Martín Molezuelas, Jon Lasa-Alonso +3
High refractive index dielectric spheres present remarkable light-scattering properties in the spectral range dominated by dipolar modes. However, most of these properties are abse…
Symmetry-protection of multiphoton states of light
Jon Lasa-Alonso, Martin Molezuelas, J. J. Miguel Varga +3
In this manuscript we analyze the emergence of protected multiphoton states in scattering problems with cylindrical symmetry. In order to do that, we first provide a formal definit…
Kerker Conditions Upon Lossless, Absorption, and Optical Gain Regimes
Jorge Olmos-Trigo, Cristina Sanz-Fernández, Diego R. Abujetas +6
The directionality and polarization of light show peculiar properties when the scattering by a dielectric sphere can be described exclusively by electric and magnetic dipolar modes…
Surface-Enhanced Circular Dichroism spectroscopy on periodic dual nanostructures
Jon Lasa-Alonso, Diego R. Abujetas, Alvaro Nodar +5
Increasing the sensitivity of chiral spectroscopic techniques such as circular dichroism (CD) spectroscopy is a current aspiration in the research field of nanophotonics. Enhancing…
