Orbital angular momentum of spatiotemporal vortices: a ray-mechanical analogy
Sophie Vo, Konstantin Y. Bliokh, Miguel A. Alonso
Spatiotemporal vortex pulses (STVPs) are wavepackets that carry transverse orbital angular momentum (OAM), whose proper quantification has been the subject of recent debate. In thi…

Closed forms for spatiotemporal optical vortices and sagittal skyrmionic pulses
S. Vo, R. Gutiérrez-Cuevas, M. A. Alonso
Spatiotemporal optical vortices (STOVs) are short pulses that present a vortex whose axis is perpendicular to the main propagation direction. We present analytic expressions for th…

Ray and caustic structure of Ince-Gauss beams
Rodrigo Gutiérrez-Cuevas, Mark R. Dennis, Miguel A. Alonso
The Ince-Gauss beams, separable in elliptic coordinates, are studied through a ray-optical approach. Their ray structure can be represented over a ray-Poincaré sphere by generalize…
