Sorting light's radial momentum and orbital angular momentum with a parabola-like lens
Yuan Li, Ye Xing, Wuhong Zhang +1
The orbital angular momentum and radial momentum both describe the transverse momentum of a light field. Efficient discriminating and sorting the two kinds of momentum lies at the…
