A team of researchers from the University of Cambridge have recently developed a room-temperature continuous-wave topological Dirac vortex microcavity. This breakthrough technology could revolutionise the way light is used in computing and other applications. The team has developed a device that is able to generate a helical beam of light, and this helical beam is able to maintain its shape even when it is subjected to external perturbations. This breakthrough is a major step towards the development of powerful, low-cost and energy-efficient computing systems. The device could be used to create fast, efficient and reliable computing systems with the potential to revolutionise the electronics industry.
