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…

Phase-resolved measurement of entangled states via common-path interferometry
Andrew A. Voitiv, Mark T. Lusk, Mark E. Siemens
We propose and experimentally demonstrate a method to directly measure the phase of biphoton states using an entangled mode as a collinear reference. The technique is demonstrated…

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…
