METATOYs are regular structures of optical elements that change the direction of light rays according to various generalized refraction laws. They may introduce discontinuities into transmitted wavefronts and create ray fields that do not have wave-optical analogies.

Topological Optics Light has several degrees of freedom (wavelength, polarization, pulse length, and so on) that can be used to encode information. A light beam or pulse can also be structured to have the property of orbital angular momentum, becoming a vortex.

Optical vortices are always created or annihilated in pairs with opposite topological charges. However, the presence of such a vortex dipole does not directly indicate whether they are associated with a creation or an annihilation event. Here we propose a method to distinguish between vortex dipoles that have just been created and those that are about ...
