Illustration of OAM Modes

Caption

Vortex lasers are named for the way light spirals around their axis of travel, thanks to a property known as orbital angular momentum, or OAM. Different OAM modes correspond to the direction and spacing of those spirals, and given a sensitive enough laser and detector, could be another property in which information could be transmitted.
