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.
