Complex optical vortex knots

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
The curves of zero intensity of a complex optical field can form knots and links: optical vortex knots. Both theoretical constructions and experiments have so far been restricted to the very small families of torus knots or lemniscate knots.
