Theoretical study of vortex beam generation based on geometric coordinate transformation

HIGHLIGHTS

• who: COPYRIGHT et al. from the University of Padua, Italy have published the research: Theoretical study of vortex beam generation based on geometric coordinate transformation, in the Journal: (JOURNAL)
• what: In this paper, a new method for generating vortex beams with continuously tunable TCs is proposed based on the principle of GCT.
• how: By changing ℓ as a fraction between 4 and 5 the authors generate the vortex beams with GCT and the results are shown in Figure 5. By setting the TC ℓ=3 5 8 10 and 15 the phase gradient exp (i . . .
