Abstract

A spatially incoherent white light optical vortex is generated using a tunable liquid crystal q-plate and white lamp source. This work investigates the propagation of incoherent vector vortex to the far field, and makes comparisons with a coherent optical vortex at a particular wavelength. The contrast ratio between the vortex’s ring and core darkness is determined, and the polarization of the vortex s mapped. For the keywords, select up to 8 key terms for a search on your manuscript's subject.
