Monopoles of orbital angular momentum (OAM) are a tantalizing prospect for orbitronics because OAM is uniform in all directions. This would mean that information flows could be generated in any ...

These orbital angular momentum (OAM) states have the potential to vastly increase bandwidth, but they are difficult to handle. Some recent research, however, suggests that we might well be using ...

Orbital angular momentum rotates a light beam’s wavefront around its propagation axis, giving it a corkscrew shape. Individually, the two types of angular momentum come in multiples of the reduced ...

The proposed diffractive deep neural network employs orbital angular momentum encoding and diffractive layers to process spatial information from handwritten digits, offering a robust and ...

The orbital angular momentum (OAM) of electromagnetic waves — a kind of “structured light” — is associated with a helical or twisted wavefront. The helical modes are characterized by a ...

Desirable among these textures, is a spherical collection of orbital angular momentums, with axis pointing to the centre, dubbed the orbital angular momentum monopole. These could exist in two states, ...
