Researchers in the United States and Israel have created infinite-capacity wireless vortex beams that can carry 2.5 terabits per second – that’s enough to transmit seven full Blu-ray movies every second. This may be the fastest wireless network ever created, a breakthrough that could revolutionize the development of faster wireless and fiber-optic networks.
Scientists have been “twisting” light since the 1970s. Light can be contorted around like a corkscrew around its axis of travel, causing the light waves at the axis itself to cancel each other out. This creates an “optical vortex” when projected onto a flat surface. This vortex can be assigned a number based on how many twists the light does in one wavelength – a number that’s either positive or negative depending on the twist. The higher the number, the faster the light is twisting.
Scientists have been wanting to exploit this phenomenon for quite time, as a way of transmitting information. And now, it appears they’ve done it.
