- Title
- The optical Hall effect in tightly focused light beams
- Author(s)
- Bomzon, Ze'ev; Gu, Min
- Abstract
- We show that topological charge is not conserved in tightly focused beams. Conversion of spin angular momentum into orbital angular momentum occurs through a geometrical phase. We demonstrate a connection between the shape of the focal spot, and the recently discovered optical Hall effect.
