Giving light a new twist with standard optical fibres: rainbow Archimedean spiral emission

F. Mangini, M. Ferraro, M. Zitelli +8

We demonstrate a new practical approach for generating multicolour spiral-shaped beams. It makes use of a standard silica optical fibre, combined with a titled input laser beam. Th…
