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…
The Anatomy of Geometric Phase for an Optical Vortex Transiting a Lens
Mark T. Lusk, Andrew A. Voitiv, Chuanzhou Zhu +1
We present an analytical means of quantifying the fractional accumulation of geometric phase for an optical vortex transiting a cylindrical lens. The standard fiber bundle of a Sph…
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…
Dynamics of elliptical vortices in a trapped quantum fluid
Chuanzhou Zhu, Mark E. Siemens, Mark T. Lusk
The nonequilibrium dynamics of vortices in 2D quantum fluids can be predicted by accounting for the way in which vortex ellipticity is coupled to the gradient in background fluid d…
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…
