Helical light

Researchers have known for some time of monochromatic light beams, such as Laguerre-Gauss beams, which carry orbital angular momentum also have a helical phase profile. According to Ole Steuernagel of the University of Hertfordshires Science and Technology Research Institute, UK, have helical wave fronts and can be made visible using interferometry. Such dark helices can […]
