A team from Singapore and China developed a 3D printed nano optical security label using coloured Orbital Angular Momentum (OAM) beams for anti-counterfeiting, offering 33^100 combinations. By exploiting structured light and miniaturizing the technology, they created a highly secure label smaller than a hair's diameter. This innovation can enhance product security across various industries, from jewelry to medicine, combating the global issue of counterfeit goods. It signifies a leap in optical anti-counterfeiting by utilizing incoherent light sources, like sunlight, for generating secure optical signals. The technology paves the way for advanced security applications in fields such as communication and quantum computing.
