Transformation of topological optical states via spiral modulation in fractional-diffraction systems
Dongdong Wang, Xueqing He, Rujiang Li +3
We propose a scheme for manipulations of a variety of topological states in fractional optical systems through spiral modulation of the local refraction index. An analytical approx…
