Helicity, chirality and spin of optical fields without vector potentials
Andrea Aiello
Helicity , chirality , and spin angular momentum are three physical observables that play an important role in the study of optical fields. These quantities are…
One more time on the helicity decomposition of spin and orbital optical currents
Andrea Aiello
The helicity representation of the linear momentum density of a light wave is well understood for monochromatic optical fields in both paraxial and non-paraxial regimes of propagat…
Measuring the non-separability of spatially disjoint vectorial fields
Andrea Aiello, Xiao-Bo Hu, Valeria Rodríguez-Fajardo +4
Vectorial forms of structured light that are non-separable in their spatial and polarisation degrees of freedom have become topical of late, with an extensive toolkit for their cre…
Perturbation theory of nearly spherical dielectric optical resonators
Julius Gohsrich, Tirth Shah, Andrea Aiello
Dielectric spheres of various sizes may sustain electromagnetic whispering-gallery modes resonating at optical frequencies with very narrow linewidths. Arbitrary small deviations f…
Microsphere kinematics from the polarization of tightly focused nonseparable light
Stefan Berg-Johansen, Martin Neugebauer, Andrea Aiello +3
Recently, it was shown that vector beams can be utilized for fast kinematic sensing via measurements of their global polarization state [Optica 2(10), 864 (2015)]. The method relie…
Observation of concentrating paraxial beams
Andrea Aiello, Martin Paur, Bohumil Stoklasa +3
We report,to the best of our knowledge, the first observation of concentrating paraxial beams of light in a linear nondispersive medium. We have generated this intriguing class of…
