Laser beams: knotted threads of darkness

By Jonathan Leach, Mark R. Dennis, Johannes Courtial and Miles J. Padgett


Destructive interference may lead to complete cancellation when light waves travelling in different directions cross, and in three-dimensional space this occurs along lines that are vortices of electromagnetic energy flow. Here we confirm theoretical predictions by experimentally creating combinations of optical laser beams in which these dark threads form stable loops that are linked and knotted
