orbital angular momentum of light

This orbital angular momentum of light can be observed in the orbiting motion of trapped particles.

Micromachines can be driven by these unique optical beams due to their intrinsic rotating mechanism due to the spin and orbital angular momentum of light.

Scientists debate the scientific basis and claims to novelty of a proposal to use the orbital angular momentum of light and radio waves to massively boost wireless data transfer.

The orbital angular momentum of light (OAM) is the component of angular momentum of a light beam that is dependent on the field spatial distribution, and not on the polarization.
