Measurement of nonequilibrium vortex propagation dynamics in a nonlinear medium
Patrick C. Ford, Andrew A. Voitiv, Chuanzhou Zhu +2
We observe and measure the nonequilibrium dynamics of optical vortices as a function of propagation distance through a nonlinear medium. The precession of a tilted-core vortex is q…
Trapped Vortex Dynamics Implemented in Composite Bessel Beams
Andrew A. Voitiv, Mark E. Siemens, Mark T. Lusk
The divergence-free nature of Bessel beams can be harnessed to effectively trap optical vortices in free space laser propagation. We show how to generate arbitrary vortex configura…
Quantized Optical Vortex-array Eigenstates in a Rotating Frame
Mark T. Lusk, Andrew A. Voitiv, Mark E. Siemens
Linear combinations of Bessel beams can be used to effectively trap light within cylindrical domains. Such hard traps can be used to produce states that exhibit stationary arrays o…
Experimental measurement of the geometric phase of non-geodesic circles
Andrew A. Voitiv, Mark T. Lusk, Mark E. Siemens
We present and implement a method for the experimental measurement of geometric phase of non-geodesic (small) circles on any SU(2) parameter space. This phase is measured by subtra…
The Peripheral Vortex Biome of Confined Quantum Fluids and Its Influence on Vortex Pair Annihilation
Chuanzhou Zhu, Patrick C. Ford, Mark E. Siemens +1
The self-annihilation of oppositely charged optical vortices in a quantum fluid is hindered by nonlinearity and promoted by radial confinement, resulting in rich life-cycle dynamic…
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…
