Abstract
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 flow1. Here we confirm theoretical predictions2,3 by experimentally creating combinations of optical laser beams in which these dark threads form stable loops that are linked and knotted.Keywords
