Cylindrical vortex vector beam
Web1.Introduction. Vortex beam is a special light field with a hollow dark core and spiral phase structure. The angular phase factor exp (i l ϕ) in the expression of the vortex beam represents the spiral phase structure, where l and ϕ represents the vortex beam's topological charge and azimuth angle, respectively. At the same time, each photon … WebFeb 1, 2024 · Cylindrical vector vortex (CVV) beams, complex light fields that exhibit a vector nature and carry quantized orbital angular momentum (OAM) states, have been widely investigated due to their rich applications.
