Optical Vortex Braiding with Bessel Beams
Andrew A. Voitiv, Jasmine M. Andersen, Mark E. Siemens +1
We propose the braiding of optical vortices in a laser beam with more than 2π rotation by superposing Bessel modes with a plane wave. We experimentally demonstrate this by using a…
Hydrodynamics Explanation for the Splitting of Higher-charge Optical Vortices
Andrew A. Voitiv, Jasmine M. Andersen, Patrick C. Ford +2
We show that a two-dimensional hydrodynamics model provides a physical explanation for the splitting of higher-charge optical vortices under elliptical deformations. The model is a…
Amplitude Structure of Optical Vortices Determines Annihilation Dynamics
Jasmine M. Andersen, Andrew A. Voitiv, Patrick C. Ford +1
We show that annihilation dynamics between oppositely charged optical vortex pairs can be manipulated by the initial size of the vortex cores, consistent with hydrodynamics. When s…
Hydrodynamics of noncircular vortices in beams of light and other two-dimensional fluids
Jasmine M. Andersen, Andrew A. Voitiv, Mark E. Siemens +1
The motion of noncircular two-dimensional vortices is shown to depend on a form of coupling between vortex ellipticity and the gradient of fluid density. The approach is based on t…
Efficient Modal Decomposition of Vortex Beams via Holographically Reconstructed Phase
Jasmine M. Knudsen, Samuel N. Alperin, Andrew A. Voitiv +3
We use phase-shifting digital holography to measure the amplitude and phase of twisted light. In our experiment, a spatial light modulator generates the studied vortex beams in add…
