A Collective Propagation Law of Optical Vortex Constellations and Longitudinal Sensing
Niladri Modak, Rafael F. Barros, Marco Ornigotti +1
Optical vortices are ubiquitous phenomena naturally appearing in wave physics, yet higher-order charges inherently split into constellations of lowest-order singularities at the sm…

High-order aberrations of vortex constellations
Rafael Barros, Subhajit Bej, Markus Hiekkamäki +2
When reflected from an interface, a laser beam generally drifts and tilts away from the path predicted by ray optics, an intriguing consequence of its finite transverse extent. Suc…
