Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly different spiral shape, may be used in applications such as 3D TV displays, microscopy, and as information carriers for visible light communications.
