Who said light only had to travel in boring waves or particles? Not Harvard. Its researchers have found the way to spin light into complex states that promise breakthroughs in multiple fields. They’ve designed meta-surfaces whose elaborate optics combine 2 varieties of light momentum (orbital angular and spin angular) to send light into corkscrews, spirals or even fork-like shapes. If you wish to change the light state, you simply need to modify the polarization of that light.
They’re not just for show, of course. The analysis team envisions these complex light states being very useful for quantum optics and data, that might facilitate quantum computers become a practical reality. they might also lead to high-powered imaging where a hole within the center of a light vortex could be modified to refocus on a topic.And it might also lead to better free-space optical communication which will transmit through the turbulent air and other conditions that scatter light. while It’s in the early days for this exotic light manipulation, It can prove to be an instrumental to computing within a long run.
