Flat variable liquid crystal diffractive spiral axicon enabling perfect vortex beams generation
A transparent variable diffractive spiral axicon (DSA) based on a single LC cell is presented. The manufactured DSA can be switched between 24 different configurations, 12 convergent and 12 divergent, where the output angle is varied as a function of the applied topological charge. The active area o...
