Two-step phase-shifting interferometry for phase-resolved imaging from a spatial light modulator
Lark E. Bradsby, Andrew A. Voitiv, Mark E. Siemens
We demonstrate two-step phase-shifting interferometry (holography) of complex laser modes generated by a spatial light modulator (SLM), in which the amplitude and phase of the sign…
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…
Tilted Poincaré Sphere Geodesics
Andrew A. Voitiv, Mark T. Lusk, Mark E. Siemens
We provide the first experimental demonstration of geometric phase generated in association with closed Poincaré Sphere trajectories comprised of geodesic arcs that do not start, e…
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…
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…
