In the last three decades, light's orbital angular momentum (OAM) has been of great interest
because it has unique characteristics that make it sought after in many research fields …

Helical light fields may carry both orbital angular and spin angular momentum which is
respectively associated with their helical wavefronts (optical vortices) and rotating transverse …

Orbital angular momentum can be used to implement high capacity data transmission
systems that can be applied for classical and quantum communications. Here we …

Spatial modes of light constitute valuable resources for a variety of quantum technologies
ranging from quantum communication and quantum imaging to remote sensing …

Orbital angular momentum (OAM) states of photons span a high-dimensional Hilbert space,
and by using it, higher information capacity and enhanced security can be achieved for both …

In this Letter, we investigate the effect of orbital angular momentum (OAM) on elastic photon-
photon scattering in a vacuum for the first time. We define exact solutions to the vacuum …

Smith–Purcell radiation (SPR) is the electromagnetic wave generated by free electrons
passing above a diffraction grating, and it has played an important role in free-electron light …

In this article, we showcase the experimental results of methods to produce and characterize
orbital angular momentum (OAM) carrying high-power lasers. The OAM pulses were …

Stimulated-emission tomography (SET) is an excellent tool for characterizing the process of
spontaneous parametric down conversion (SPDC), which is commonly used to create pairs …

The structured vector fields of circularly polarized light, comprising both left and right (RCP
and LCP) beams superposed in the atomic medium are investigated in this work. At …
