Twisted beams of light may illuminate a straight path to more secure and higher capacity communications. A new type of photodetector developed at Harvard’s School of Engineering and Applied Sciences (SEAS) allows systems to judge these beams by their spin rate. It will allow the encoding of an infinite amount of numbers in those data streams, which offers the potential for dramatically larger data rates as well as better encryption.
