Pump-tailored Alternative Bell State Generation in the First-Order Hermite-Gaussian basis
Zhe Kan, Andrew A. Voitiv, Patrick C. Ford +2
We demonstrate entangled-state swapping, within the Hermite-Gaussian basis of first-order modes, directly from the process of spontaneous parametric down-conversion within a nonlin…
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…
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…
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…
Fast phase cycling in non-collinear optical two-dimensional coherent spectroscopy
Maria F. Munoz, Adam Medina, Travis M. Autry +5
As optical two-dimensional coherent spectroscopy (2DCS) is extended to a broader range of applications, it is critical to improve the detection sensitivity of optical 2DCS. We deve…
Hidden Silicon-Vacancy Centers in Diamond
Christopher L. Smallwood, Ronald Ulbricht, Matthew W. Day +7
We characterize a high-density sample of negatively charged silicon-vacancy (SiV) centers in diamond using collinear optical multidimensional coherent spectroscopy. By comparin…
Diagonal Slice Four-Wave Mixing: Natural Separation of Coherent Broadening Mechanisms
Geoffrey M. Diederich, Travis M. Autry, Mark E. Siemens
We present an ultrafast coherent spectroscopy data acquisition scheme that samples slices of the time domain used in multidimensional coherent spectroscopy to achieve faster data c…
Quantum Turbulent Structure in Light
Samuel N. Alperin, Abigail L. Grotelueschen, Mark E. Siemens
The infinite superpositions of random plane waves are known to be threaded with vortex line singularities which form complicated tangles and obey strict topological rules. We obser…
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…
The Angular Momentum of Topologically Structured Darkness
Samuel N. Alperin, Mark E. Siemens
We theoretically analyze and experimentally measure the extrinsic angular momentum contribution of topologically structured darkness found within fractional vortex beams, and show…
The Centroid Shifts of Light Beams Reflected from Multi-Layers and the Effects of Angular Momentum Manifestations
Mark T. Lusk, Mark E. Siemens, Guillermo F. Quinteiro
Laguerre-Gaussian (LG) beams reflected from a multi-layered dielectric experience a shift in their centroid that is different than that from a single interface. This has been previ…
Efficient Thermal Conductance in Organometallic Perovskite CH3NH3PbI3 Films
Qi Chen, Chunfeng Zhang, Mengya Zhu +10
Perovskite-based optoelectronic devices have shown great promise for solar conversion and other optoelectronic applications, but their long-term performance instability is regarded…
