Abstract

We report on the theoretical and experimental demonstration of a geometrical representation for nondiffracting beams with orbital angular momentum. This representation is a SU(2) structure equivalent to the Poincare sphere for the polarization states of light, which describes the different states of light beams possessing orbital angular momentum in terms of nondiffracting beams. We have also investigated unitary transformations within our geometrical representation using linear optical elements, equivalent to a polarization state rotation on the Poincare sphere. A new class of nondiffracting beams is also suggested.
