"Twisting light means photons have a quantum characteristic called orbital angular momentum (OAM). Photons with OAM have electric and magnetic fields that corkscrew rather than oscillate in a plane. There are a theoretically infinite number of OAM values, and multiple beams having different orbital angular momentums can occupy the same fiber, allowing more data to be transferred." --quote from article
