Abstract
We will discuss some of our recent results on fractional scalar and vector vortex beams representing the Hilbert Hotel paradox. Using full Poincare Bessel beams (FPB), we showed that one can create an infinite series of C-point singularities. We have also devised a novel method to measure the polarization coverage of Poincare beams and showed that the FPBs are the superposition of an infinite number of Poincare beams.
