Among all the degrees of freedom of photons, orbital angular momentum (OAM ... which converts the Gaussian beam to the OAM beam. In the characterization of the prepared hybrid state, they measure ...

Researchers have developed a 3D-printed device that generates twisting light beams with orbital angular momentum (OAM), a form of rotational energy that can carry more data than regular beams. The ...

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 ...

The orbital angular momentum (OAM) carried by the vortex ... structure distribution of a partially coherent Laguerre Gaussian beam in the far field consists of a series of concentric dark ring ...

This study explores the propagation properties of orbital angular momentum (OAM) carried by a vector anomalous ... A comparative analysis is conducted between the VAVB and Laguerre-Gaussian beam, ...

integrated light source that simultaneously produces multiple laser beams with different, very high orbital angular momenta has been unveiled by US researchers. The technology may mark a significant ...

The conditions for formation of vortex beams with the given value of the orbital angular momentum are determined. The information coding by the OAM value is demonstrated in laboratory experiments.

However, for the radial indices of Laguerre-Gaussian beam, it is seldom investigated in the optical communication systems. Here, we try to establish a novel OAM encoding system with high-order radial ...
