Researchers Discover New Form of Light for Secure Optical Communication

Future Optical communications might be more secure thanks to Professor John Donegan and team for their research conducted at the Trinity College in Dublin, Ireland. The research team found a new property of light while passing it through crystals. Usually, when light hits our eyes, the spinning photons twist infinitesimally. In Quantum physics, the force of the twist/spin called the angular momentum has been thought to be a direct multiple of a constant called Planck’s constant. However, John Donegan and team discovered a new form of light with an angular momentum that is exactly half of the conventional one. The team believes the new discovery would have practical applications in secure optical communication.
